SBC Intake Gasket Set

The SBC Intake Gasket Set from Air Flow Research is a critical sealing component engineered for small-block Chevy engines requiring reliable intake manifold-to-cylinder head isolation. As a mechanic rebuilding or maintaining a classic or performance SBC, you know that even minor coolant or vacuum leaks can compromise engine efficiency, fuel economy, and overall reliability. This pair of composite gaskets addresses that need with precision-engineered rectangular port geometry designed to match factory and aftermarket intake manifold port dimensions.

Built from composite material, the SBC Intake Gasket Set delivers superior durability and chemical resistance compared to traditional cork or paper gaskets, resisting engine oil, coolant, and fuel degradation over extended service intervals. The 2.23 x 1.33 inch rectangular port profile matches the flow characteristics of modern small-block heads and high-flow manifolds, ensuring a complete seal without restricting air or coolant circulation. Composite construction also provides better conformability to machined surfaces, reducing the risk of compression set and repeat failures—a common issue with inferior gasket materials in high-heat engine bays.

This set suits any small-block Chevy application, from stock 350s to stroker builds and carbureted or EFI conversions. Whether you're performing a top-end refresh, upgrading to an Edelbrock or Holley intake, or simply replacing failed OEM gaskets, the Air Flow Research SBC Intake Gasket Set delivers the sealing integrity you need without the ongoing maintenance headaches of budget alternatives. Installation is straightforward: clean the mating surfaces thoroughly, apply a thin bead of gasket sealer if desired, and torque fasteners to specification. Proper surface prep ensures these gaskets will hold pressure and temperature cycling for years of dependable engine operation.
