Intake Gasket Set - 55-86 SBC

The Intake Gasket Set - 55-86 SBC by Edelbrock is an essential sealing component for small-block Chevy engines running aftermarket or factory intake manifolds. Whether you're rebuilding a classic engine, upgrading your carburetor setup, or troubleshooting intake vacuum leaks, this gasket kit provides reliable compression and fuel mixture containment where the manifold meets the cylinder head. Small-block Chevrolet engines are workhorses in street machines, drag cars, and restorations, and a quality intake gasket set is non-negotiable for preventing coolant weeping, air leaks, and unmetered fuel entry.

This kit features composite gasket material rated at 0.06 inches thick, engineered to withstand intake manifold clamping loads without crushing or extruding under pressure. The rectangular port design measures 1.28 by 2.09 inches, matching the standard SBC intake port profile used across generations from 1955 to 1986. Composite construction offers superior sealing compared to fiber gaskets alone, resisting coolant degradation and maintaining dimensional stability across thermal cycles—critical when carburetors pull vacuum and cylinder pressures spike during acceleration or load. The gasket set format ensures you receive matched pairs sized for proper port-to-port alignment, eliminating guesswork during reassembly.

Mechanics and engine builders gravitate to Edelbrock gasket sets because they fit both factory and Edelbrock performer-series manifolds, as well as most common aftermarket options designed for small-block Chevy applications. Installation is straightforward: clean mating surfaces thoroughly, apply gasket sealer if desired, position the kit, and torque the manifold bolts to specification in a cross pattern. This product is indispensable when converting to a new intake manifold, performing a top-end rebuild, or stopping stubborn vacuum leaks that plague carbureted and early fuel-injected small-block engines.
