About this part

Product Details

If you're rebuilding the top end of your Chevrolet Gen-1 Small Block V8, getting the head gasket right is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built for engines with a 4.060 inch bore and is designed to work with either 18 or 23-degree cylinder heads. It has a compressed operating thickness of .056 inches, which is important for maintaining proper compression ratios.

Cometic uses multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes, ensuring a reliable seal between the head and the block. These MLS gaskets don't require any additional sealants, making installation more straightforward, and they're suitable for use with both aluminum and cast iron blocks.

This gasket fits a wide range of Chevrolet and GMC trucks, cars, and SUVs from the early 1980s, as well as Avanti and Excalibur models. It's a well-built component designed to handle the demands of high-output engines.
