Cometic Chevy Gen1 Small Block V8 .045in MLS Cylinder Head Gasket - 4.030in Bore

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Chevrolet Gen-1 Small Block V8 engines. You get one MLS head gasket with a 4.030-inch bore and a compressed operating thickness of .036 inches, built to a .045-inch uncompressed thickness. This gasket is constructed from multiple layers of stainless steel, with the outer layers coated in Viton, a heat-resistant rubber material. The center layer is uncoated stainless steel, allowing for varied thickness requirements.

MLS gaskets are known for their strength and ability to rebound, which helps them resist corrosion and handle the shearing forces between aluminum heads and cast iron blocks, or between two aluminum components. The Viton coating on the outer layers is designed to seal effectively in harsh environments and under various load conditions. These gaskets are ideal for high-output engines and do not require sealants, making installation more straightforward.

This gasket fits a wide range of vehicles, including many Chevrolet and GMC trucks and cars from the early 1980s, as well as Avanti and Excalibur models. It's a solid option when rebuilding or upgrading your Gen-1 Small Block V8 engine.
