Cometic Chevy Gen-1 Small Block V8 .040in MLS Cylinder Head Gasket - 4.040in Bores

When you're rebuilding the top end of your Chevy Gen-1 Small Block V8, a solid head gasket is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is designed for a 4.040-inch bore and is .040 inches thick, suitable for 18/23 degree cylinder heads. It fits a wide range of vehicles, including models like the Chevrolet Camaro, GMC C1500, and Buick Regal from the early to mid-1980s.

Cometic builds these gaskets with three to five layers of stainless steel. This material choice gives the gasket strength and helps it rebound well while resisting corrosion. The outer layers are embossed and then coated on both sides with a Viton rubber material. This coating is tough enough for various demanding sealing conditions and surface finishes, and it can handle temperatures up to 482°F (250°C), making it a well-built option for your engine build.
