Cometic Chevrolet Gen-1 Small Block V8 .080in MLS Cylinder Head Gasket - 4.125in Bore

If you're rebuilding the top end of your Chevrolet Gen-1 Small Block V8, a reliable head gasket is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built for that job, featuring a .080 inch thickness and a 4.125 inch bore, making it suitable for many aftermarket cylinder heads where custom water port sizing might be needed.

Cometic uses multiple layers of stainless steel for strength and resistance to corrosion, which also helps the gasket rebound effectively under pressure. The outer layers are treated with a Viton rubber coating on both sides. This coating is heat resistant up to 482°F and is designed to handle tough sealing conditions, ensuring a solid seal even with different surface finishes on your heads and block. The water ports are intentionally undersized to allow for custom porting to match your specific aftermarket heads.

This gasket fits a wide range of Chevrolet and GMC trucks, cars, and performance models from 1980 through 1986, including popular vehicles like the Chevrolet C10 and Camaro. It's a well-built component for anyone looking to ensure a proper seal during their engine build.
