About this part

Product Details

This product includes one Cometic Multi-Layer Steel (MLS) cylinder head gasket, designed for Chevy Gen-1 Small Block V8 engines with a 4.100 inch bore and 18/23 degree cylinder heads. These gaskets are built with multiple embossed layers of stainless steel, featuring an outer layer coated with Viton rubber. This construction offers excellent sealing performance for high-output engines and is suitable for use with both aluminum and cast iron blocks, helping to manage the shearing forces that can occur between different metals.

The MLS design provides increased strength and resistance to corrosion, with the stainless steel layers allowing the gasket to rebound. The Viton coating on the outer layers is a heat-resistant elastomer capable of withstanding temperatures up to 482 degrees Fahrenheit, making it well-suited for demanding sealing environments. The center layer is uncoated stainless steel and can be varied in thickness to meet different engine requirements; this specific gasket has a compressed operating thickness of .120 inches. Because of their robust construction, these gaskets do not require additional sealants.

This gasket fits a wide range of vehicles, including models like the Chevrolet Camaro, GMC C1500, and Buick Regal from the early to mid-1980s. It's a solid option when rebuilding or refreshing the top end of your Gen-1 Small Block V8.
