About this part

Product Details

This product is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Chevy Gen-1 Small Block V8 engines. It features a 4.165-inch bore and a compressed thickness of 0.036 inches, with an uncompressed thickness of 0.056 inches. This gasket is built to handle the demands of high-output engines and is suitable for use with both aluminum and cast iron blocks, as well as aluminum heads. It fits a wide range of vehicles from the early 1980s, including models like the Chevrolet Camaro, GMC C1500, and Buick Regal.

The gasket is constructed from multiple embossed layers of stainless steel, which provides increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482 degrees Fahrenheit. This coating is designed to perform well in harsh sealing environments and under various load conditions. The center layer is uncoated stainless steel, allowing for adjustments to thickness requirements. Because it's an MLS gasket, it doesn't require any additional sealants for installation.
