SBC Intake Gasket Set 1971-1986

The SBC Intake Gasket Set 1971-1986 is a genuine Chevrolet Performance intake manifold gasket kit engineered for small-block Chevy engines across three decades of production. Whether you're rebuilding a carbureted 350 or refreshing a 327, this gasket set seals the critical junction between your intake manifold and cylinder head—a failure point that costs power and causes coolant leaks if overlooked during any engine work.

This kit features 0.075-inch-thick steel-core laminate gaskets with rectangular port geometry sized at 1.273 x 2 inches, matching the port dimensions of small-block casting heads from the 1971–1986 era. The steel core provides durability under thermal cycling and intake manifold bolt pressure, resisting blowout and maintaining a gas-tight seal across the entire power band. The laminate construction offers superior gasket recovery compared to solid rubber or cork, critical for maintaining compression and preventing vacuum leaks that compromise idle quality and fuel economy.

Any engine builder, restorer, or enthusiast performing intake manifold removal—whether for valve-cover gasket service, cylinder head work, or carburetor maintenance—needs a fresh gasket set to guarantee a reliable seal on reinstallation. Original equipment gaskets deteriorate with age and heat cycling, making replacement essential for vintage and classic Chevrolet engines. Always install these gaskets dry with a light coating of gasket sealer on both sides and torque manifold bolts in a cross pattern to specification for optimal clamping force and seal integrity.
