About this part

Product Details

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Chevrolet Gen-1 Small Block V8 engines, specifically those equipped with Vortec heads. It features a compressed operating thickness of 0.027 inches and a bore size of 4.165 inches, making it suitable for a wide range of popular vehicles from the early 80s, including models like the Chevrolet C10 and Camaro, as well as GMC C1500 trucks.

Cometic builds these gaskets with 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 conditions and various surface finishes without needing additional sealants. This construction is ideal for pairing aluminum heads with either aluminum or cast iron blocks, as it can manage the shearing forces that can occur between different metals.
