Product Details

If you're rebuilding the top end of your Chevy Gen 1 Small Block V8, a solid set of head gaskets is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the pressures of performance engines, offering a reliable seal for a wide range of GM vehicles from the early 80s, like the Chevrolet C10 or GMC C1500, up through 1986.

Cometic uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes, ensuring a tight seal against both aluminum and cast iron blocks. With a compressed thickness of .120 inches and a 4.125-inch bore, these gaskets are designed to fit engines with 18/23 degree cylinder heads and include steam holes to help manage heat.

Because they are made from multiple layers of steel and coated with Viton, these MLS gaskets don't require any additional sealants, making installation more straightforward. They are a well-built option for anyone looking to ensure a strong seal in their rebuilt small block Chevy.
