Cometic Big Block Chevy Cylinder Head Gaskets

Cometic BBC head gaskets are made from three to five layers of stainless steel, which provides excellent corrosion resistance. These gaskets also handle extreme cylinder pressures from high performance and racing engines, including those using a supercharger, turbocharger, or nitrous oxide system. Due to the high quality materials and assembly, Cometic gaskets do command a higher price. They also will not work with engines using O-rings or receiver grooves.

The best BBC MLS head gasket from Cometic depends on the application and engine needs. These include the engine type, bore size, and thickness.

Cometic BBC head gaskets start at just over $85 each and reach around $225 each, depending on the application.
