Intake Gasket Set SBC w/18 Degree Heads

The Intake Gasket Set SBC w/18 Degree Heads from Cometic Gaskets is engineered for small block Chevy engines running modern 18-degree cylinder head designs. This pair of intake manifold gaskets seals the critical junction between your intake manifold and cylinder heads, preventing vacuum leaks, coolant seepage, and combustion gas bypass that would otherwise compromise engine efficiency and reliability. Whether you're rebuilding a performance street engine or freshening a stock platform, a quality intake gasket set is non-negotiable for proper sealing and longevity.

Cometic's composite construction delivers superior performance over traditional cork or felt designs, offering excellent chemical resistance and dimensional stability across repeated heat cycles. The 0.06-inch thickness is precisely engineered to match 18-degree head geometry and accommodate modern intake manifold designs with 2.2 x 1.3-inch rectangular ports. This material composition resists fuel, oil, and coolant degradation while maintaining a consistent seal pressure, critical for maintaining air-fuel ratio accuracy and preventing boost leak on forced-induction builds. The compact 5.1 x 21.6-inch gasket profile ensures proper fitment without modification or custom machining.

Professional engine builders and weekend enthusiasts alike rely on Cometic gasket sets for restorations, engine swaps, and high-mileage rebuilds where OEM sealing has failed. The dual-gasket design (sold as a pair) covers both intake ports on a small block Chevy configuration, simplifying the purchase process and ensuring matched sealing performance. Installation is straightforward during any intake manifold removal, and these gaskets pair seamlessly with both stock and performance manifolds. For anyone serious about maintaining proper engine sealing and avoiding vacuum leaks that trigger check-engine codes, this intake gasket set is a reliable, cost-effective solution for small block Chevy platforms.
