Best Intake Manifold For Vortec Heads: Compare 10 Options
A strong intake manifold for Vortec heads should match the head’s bolt pattern, suit the engine’s operating range, and fit the intended carburetor setup; the JGhyperX 7516 52028 Air-Gap is a well-specified choice for street-oriented small-block builds. This roundup compares ten listed options for SBC Vortec applications, including dual-plane designs aimed at lower operating ranges and single-plane models intended for higher RPM use. Product details vary: some listings specify RPM range, manifold height, and carburetor compatibility, while others provide only basic fitment or replacement references.
Check the engine, head bolt pattern, carburetor bore, and clearance before ordering, and confirm included adapters or gaskets rather than assuming they come in the box. The rankings prioritize stated Vortec fit, useful specifications, and installation details.
The JGhyperX 7516 52028 Air-Gap leads because its listing specifically identifies Gen 1 small blocks with Vortec-style heads, a dual-plane design, and a 1,500–6,500 RPM range. It also provides a 4.650-inch manifold height and recommends 0.120-inch intake gaskets, giving buyers more fitment detail than many competing listings. It best suits a carbureted SBC build seeking a broad operating range; verify your exact head, carburetor, and clearance before purchase.

- Weight: 15.47 lb
- Package Dimensions: 21.5 x 12.3 x 5.5 in
Best for: Spread-or-square-bore carb setups.
Why it ranks #3: The listing names 1996–2002 305 and 350 Vortec engines, accepts spread- or square-bore carbs, and specifies an idle-to-5,500-RPM range.
Support for either spread-bore or square-bore carburetors sets this Htostar Racing dual-plane manifold apart for compatible 1996–2002 Vortec small-block builds. The listed 305 and 350 applications and idle-to-5,500 RPM operating range help define its engine and use-case boundaries.

#4 · Highest Listed Range
4. Pateyney Satin Dual Plane
- Weight: 16.27 lb
- Package Dimensions: 22 x 12.25 x 5.5 in
Best for: Higher-range stock-deck Vortec builds.
Why it ranks #4: This carbureted dual-plane manifold lists idle to 6,500 RPM and a 4.500-inch height, with a clear warning to verify the eight-bolt Vortec pattern.
The idle-to-6,500 RPM range is the headline for this Pateyney dual-plane aluminum manifold, giving carbureted Vortec SBC buyers a clearly stated operating window. Its 4.500-inch height and stock/OEM standard-deck style add practical dimensions for evaluating installation space and engine configuration.
The complete-engine-block intake section and single-carburetor configuration clarify the intended arrangement, while the 4.500-inch height helps with clearance planning. The manifold is listed for Vortec heads with eight intake bolts, two at each corner; the supplied note explicitly rules out heads with twelve total bolts.

6. OXYSTAR 2028 Dual Plane
- Weight: 17.96 lb
- Package Dimensions: 22.1 x 11.1 x 6.5 in
Best for: Broad small-block engine coverage.
Why it ranks #6: The title specifies a dual-plane 2028/7516/52028 design for Chevy Vortec SBC engines and a 1,500–6,500-RPM range, though carburetor details are limited.
Compatibility spanning Chevy Vortec 1996-up SBC 283, 307, 327, and 350 engines is the key differentiator for this OXYSTAR dual-plane air-gap manifold. Its listed 1,500–6,500 RPM range gives buyers a clear operating window to compare with their intended carbureted engine use.
The title identifies four small-block displacements, a useful starting point for buyers whose build is not limited to a 350. Pair that broad application list with the dual-plane air-gap layout and stated 1,500–6,500 RPM window to assess whether the manifold matches the engine’s intended operating range.

7. Woosphy 2007 Dual Plane
- Weight: 14.97 lb
- Package Dimensions: 21.1 x 11.1 x 5.2 in
Best for: Replacement buyers with listed 305 or 350.
Why it ranks #7: Its listing identifies replacement fit for 1996-on 305 and 350 Chevy small-block Vortec engines, but gives few operating or installation specifications.
Explicit 1996-onward Chevy small-block Vortec 305 and 350 replacement applications are the key information for this Woosphy dual-plane manifold. The listing also supplies reference number 82007, giving replacement shoppers a part identifier to compare with their existing application details.
The compatibility description names both 5.0L/305 and 5.7L/350 V8 Chevy Small Block Vortec engines from 1996 onward, providing a focused application check for replacement use. Its dual-plane designation identifies the intake layout, while reference OEM number 82007 gives another point of comparison during parts selection. The supplied details do not state an RPM range, manifold height, material, or carburetor style, so those criteria cannot be assessed from this listing information.
- Lists 1996-onward Chevy Vortec 5.0L/305 applications
- Lists 1996-onward Chevy Vortec 5.7L/350 applications
- Dual-plane intake designation
- Reference OEM number 82007 supplied
- The supplied listing does not state an operating RPM range.
Skip it if you need a stated RPM window and aluminum construction; JGhyperX 7516 52028 lists both.
This is a focused replacement candidate for the listed 1996-onward Chevy Vortec 305 or 350. Use its application description and 82007 reference as boundaries; the supplied details leave operating range and dimensions unspecified.

A detailed vehicle list distinguishes this NEWZQ replacement manifold: it names Cadillac Escalade, Chevy and GMC C/K trucks, Suburbans, Yukon, and Savana applications across specified model years. That makes its application references more useful to replacement buyers than a general small-block description alone.
The supplied OE reference numbers—2028, 22028, PC22028, and 52028—give replacement shoppers several identifiers to compare against their existing part. Listed applications include 1996–1999 Chevy and GMC C/K trucks and Suburbans, 1996–2000 Escalade and Yukon, and 1996–2002 Savana, alongside Cadillac Vortec cylinder heads. Its stated 1,500–6,500 RPM range adds an operating reference, but the fitment list should guide application selection.
- Lists multiple OE reference numbers for replacement comparison
- Names Chevy and GMC C/K truck applications
- Includes listed Escalade, Suburban, Yukon, and Savana applications
- States a 1,500–6,500 RPM range
- The supplied listing gives no manifold material or carburetor-mount details.
Skip it if you need stated dual-plane and air-gap construction; JGhyperX 7516 52028 identifies both.
This is for replacement shoppers whose vehicle matches one of the listed Cadillac, Chevy, or GMC applications and whose reference numbers align. The supplied vehicle years and application list are the key fit boundaries.

View on AmazonWhy it ranks #9: It specifies Gen 1 305 and 350 engines with Vortec-style heads and a 3,000–7,500-RPM range, but its single-plane focus suits higher-RPM use.
The listed 3,000–7,500 RPM operating range identifies this OXYSTAR 2913 as a higher-range single-plane choice for compatible Gen 1 SBC builds. Its application covers 1996–2002 305 and 350 engines with Vortec-style heads and a standard-deck block.
OXYSTAR specifies a carbureted configuration for compatible 305 and 350 V8 engines, helping buyers narrow the manifold to the stated Gen 1 Vortec-style-head application. The standard-deck-block requirement is another fit boundary to check during build planning. Its single-plane layout and 3,000–7,500 RPM range define the intended operating profile, while the listed reference numbers 2913, 2033, and 52033 give replacement shoppers identifiers to compare against their parts information.
- Single-plane layout with a 3,000–7,500 RPM range
- Listed for 1996–2002 Gen 1 305 and 350 V8 engines
- Specifies Vortec-style heads and standard-deck block
- Reference numbers 2913, 2033, and 52033 supplied
- Its stated operating range begins at 3,000 RPM.
Skip it if you need an operating range beginning at idle; Pateyney YMXDM-3202H lists idle to 6,500 RPM.
This suits a carbureted 1996–2002 Gen 1 305 or 350 build targeting its stated higher RPM range. The standard-deck block, Vortec-style heads, and 3,000 RPM lower limit are key boundaries.

View on AmazonWhy it ranks #10: This Vortec-compatible single-plane lists a 3,500–8,500-RPM range and 6.060-inch height, making it less aligned with broad lower-RPM use.
A 3,500–8,500 RPM range makes this JGhyperX single-plane manifold the high-rev option in this group. It is listed for SBC Vortec-head 305 and 350 V8 engines, with a 6.060-inch height and 2.06-by-1.18-inch intake ports to help buyers evaluate the configuration.
The single-plane layout and stated 3,500–8,500 RPM range point toward builds intended to operate at higher engine speeds than the listed street-range dual-plane options. Its 6.060-inch height is an important packaging measurement, while the 2.06-by-1.18-inch port dimensions provide specific information for comparing the intake path with a build. JGhyperX recommends 0.120-inch intake gaskets for Gen 1 small blocks using Vortec-style heads, a relevant assembly note for installation planning.
- Single-plane layout with a 3,500–8,500 RPM range
- Listed for SBC Vortec-head 305 and 350 V8 engines
- 6.060-inch manifold height specified

- Its stated 3,500 RPM lower limit is less suited to lower-range operation.
Skip it if you prioritize idle-to-6,500 RPM operation; DEEPMOTOR DM-1107P lists a dual-plane range beginning at idle.
This suits a Vortec-head 305 or 350 build targeting the stated higher RPM range, with port size and manifold height available for planning. Consider its 3,500 RPM lower limit and tall profile.

View on AmazonAvoid the Vortec Bolt-Pattern Mismatch
A bolt-pattern mismatch can prevent an otherwise suitable manifold from sealing or fitting, so identify the heads before choosing from these listings. The Pateyney Satin Dual Plane and DEEPMOTOR Black Dual Plane listings specifically warn that Vortec heads use eight intake bolts, with two at each corner, and say they will not work with a 12-bolt intake pattern. The JGhyperX 7516 Air-Gap likewise calls for Vortec-style heads and recommends 0.120-inch-thick intake gaskets.
Do not treat an engine’s displacement or model year alone as proof of head compatibility: these products span different stated application ranges and reference numbers. Compare the actual head bolt locations and gasket requirements with the exact listing, and confirm any vehicle-specific fitment separately.
The NEWZQ SBC Replacement lists vehicle applications, but its supplied details do not establish the bolt pattern or gasket dimensions for every configuration.
Dual-Plane Versus Single-Plane Trade-Off
The listed RPM ranges show why manifold layout should match the engine’s intended operating band rather than a headline performance claim. Dual-plane options include the Pateyney Low-Rise Dual Plane at idle to 5,500 RPM and the JGhyperX 7516 Air-Gap at 1,500–6,500 RPM. In contrast, the JGhyperX 2913 Air-Gap is listed for 3,500–8,500 RPM, while the OXYSTAR 2913 Single Plane is specified for 3,000–7,500 RPM.
Those figures describe the manufacturers’ stated ranges; they do not establish a guaranteed power increase or prove how a particular engine will perform. A higher-range single-plane listing is therefore not automatically the right choice for a build that needs its useful operating range lower down.
Compare the stated range with the engine’s camshaft, carburetor, gearing, and intended use, and have a builder verify the complete combination.
How to Choose a Vortec Intake Manifold
Vortec Head and Engine Fit
Start by matching the manifold to the actual Vortec-style heads and engine configuration, not just the vehicle name. JGhyperX lists Gen 1 small-block 305 and 350 compatibility; Htostar Racing specifies 1996–2002 305 and 350 Vortec engines; and OXYSTAR 2913 lists 1996–2002 Gen 1 305 and 350 engines with Vortec-style heads. The Pateyney Satin Dual Plane and DEEPMOTOR Black Dual Plane both flag the eight-bolt Vortec pattern and warn against 12-bolt intakes.
A buyer with confirmed Vortec heads can focus on these stated fits, while anyone uncertain about the head casting or bolt pattern should verify it before ordering. Broader engine or vehicle references alone do not establish fit for every swap or modified combination.
Operating RPM and Manifold Layout
Choose a listed RPM range that suits the intended engine use, and treat the range as a specification rather than a guaranteed result. Dual-plane choices span idle to 5,500 RPM for the Pateyney Low-Rise and Htostar Racing models, 1,500–6,500 RPM for JGhyperX 7516, and idle–6,500 RPM for Pateyney Satin. The single-plane JGhyperX 2913 lists 3,500–8,500 RPM, while OXYSTAR 2913 lists 3,000–7,500 RPM.
Buyers prioritizing a lower stated operating band should compare the idle-range dual-plane listings; those building for higher-RPM operation may investigate the single-plane models. The supplied data does not prove which manifold makes more power on an individual engine, so confirm the choice against the rest of the build.
Carburetor and Installation Details
Check carburetor style, included adapters, gasket guidance, and physical clearance before committing to a manifold. Htostar Racing lists compatibility with spread- or square-bore carburetors, and the Pateyney Low-Rise includes an adapter plate and gasket for square-bore use. JGhyperX 7516 specifies a 4-barrel carburetor mounting and recommends 0.120-inch intake gaskets.
The JGhyperX 2913 lists a 6.060-inch manifold height, while Pateyney Satin lists 4.500 inches; compare these figures with the available hood and accessory space for your build. Do not assume other packages include adapters or gaskets when their details do not say so.
Buyers changing carburetor type should favor listings with explicit compatibility or included conversion pieces, then verify linkage and clearance with the intended components.
Which Vortec Intake Manifold Should You Choose?
For a broadly specified carbureted Vortec SBC build, choose the JGhyperX 7516 Air-Gap: it combines stated Vortec-head fit, dual-plane layout, and a 1,500–6,500-RPM range. If your priority is an explicitly lower operating band and you need a square-bore adapter, the Pateyney Low-Rise Dual Plane lists idle-to-5,500-RPM use and includes an adapter plate and gasket. The Htostar Racing Dual Plane is another choice when spread- or square-bore carburetor compatibility matters.
For a higher-RPM combination, consider the OXYSTAR 2913 Single Plane or JGhyperX 2913 Air-Gap, whose listed ranges begin at 3,000 and 3,500 RPM respectively. Before ordering any option, verify the head bolt pattern, gasket, carburetor, and available clearance.
Frequently Asked Questions
How can I identify whether my small-block Chevy has Vortec-style intake bolt holes?
Compare the intake bolt-hole pattern on your heads with the manifold’s stated compatibility and the head manufacturer’s documentation. Do not rely on engine year or displacement alone. If the pattern is unclear, confirm the casting or head details before ordering, since a mismatch can prevent proper installation.
What gasket and sealing procedure should I use when installing a Vortec intake manifold?
Use a gasket that matches the heads and manifold, and follow the gasket and manifold makers’ sealing instructions. The JGhyperX 7516 listing recommends 0.120-inch intake gaskets, but that recommendation should not be assumed to apply to every option. Confirm fit, prepare clean mating surfaces, and follow the specified sealant procedure.
How do manifold height and carburetor choice affect hood and accessory clearance?
Manifold height, carburetor dimensions, and installed accessories all affect available clearance, so check the complete combination rather than the manifold alone. The JGhyperX 7516 listing gives a 4.650-inch manifold height. Verify that figure against your setup and check hood and accessory clearance before purchase.
How should I choose between square-bore and spread-bore compatibility?
Choose based on the carburetor you plan to use and confirm whether the manifold accepts that configuration directly or needs an adapter. The Htostar Racing listing specifies spread- or square-bore compatibility. The Pateyney Low-Rise listing includes an adapter plate and gasket; verify the fit with your carburetor.
How should I use the listed RPM range when choosing a manifold?
Treat the stated RPM range as a selection clue, then match it to your engine combination and intended use. The JGhyperX 7516 lists 1,500–6,500 RPM; the Pateyney Low-Rise lists idle to 5,500 RPM. The OXYSTAR 2913 and JGhyperX 2913 list ranges beginning at 3,000 and 3,500 RPM.
Final Words
For a broadly specified carbureted Vortec SBC build, the JGhyperX 7516 Air-Gap is the clearest choice: its listing identifies Vortec-head fit, a dual-plane layout, and a 1,500–6,500-RPM range. Consider the Pateyney Low-Rise if its lower listed operating band and included adapter suit your setup, or a listed single-plane option for a higher-RPM combination. Before ordering, verify head pattern, gasket, carburetor, and clearance.
