Cometic Chevrolet Gen-1 Small Block V8 .045in MLS Cylinder Head Gasket - 4.125in Bore

When you're rebuilding the top end of your Chevrolet Gen-1 Small Block V8, you need a head gasket that can handle the pressure. This Multi-Layer Steel (MLS) gasket from Cometic is built for high-output engines and is designed to provide a solid seal without needing any extra sealants. It's a well-built option whether you're mating aluminum heads to an aluminum block or aluminum heads to cast iron.

Cometic constructs these gaskets from multiple layers of stainless steel, which gives them increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes. The center layer is stainless steel and can be varied in thickness to meet different requirements; this particular gasket has a compressed operating thickness of 0.045 inches and a 4.125-inch bore. It's also noted for having undersized water ports, which allows for customization when used with aftermarket heads.

This gasket fits a wide range of Chevrolet and GMC V8 applications from the early 80s, including popular models like the Chevrolet C10 and Camaro, as well as GMC C1500 trucks. It's also suitable for Brodix 12-23 Degree heads.
