Cometic Chevy Gen-1 Small Block V8 .070in MLS Cylinder Head Gasket - 4.200in Bore

This product includes one Cometic Multi-Layer Steel (MLS) cylinder head gasket, designed for Chevy Gen-1 Small Block V8 engines with a 4.200-inch bore. These gaskets are built with multiple embossed layers of stainless steel, featuring an outer layer coated with Viton rubber. The compressed operating thickness is 0.036 inches. This gasket is suitable for use with aluminum heads on aluminum blocks, as well as aluminum heads on cast iron blocks, and can handle the shearing forces between different metals.

The multi-layer steel construction provides increased strength and the ability to rebound, helping to resist corrosion. The Viton coating on both sides is a heat-resistant material designed to perform well in demanding sealing environments, under various load conditions, and on different surface finishes. The center layer is stainless steel and can be varied to achieve different thickness requirements, like the 0.070-inch thickness of this specific gasket. These MLS gaskets are designed for maximum sealing performance in high-output engines and do not require additional sealants.

This gasket fits a wide range of vehicles from the early 1980s, including models like the Chevrolet C10, Camaro, and GMC C1500. It's a solid option when rebuilding or refreshing the top end of your engine.
