Product Details
This is a Cometic Multi-Layer Steel (MLS) head gasket designed for Chevrolet Gen-1 Small Block V8 engines. It's built for a 4.060 inch bore and has a compressed thickness of .040 inches, specifically made to work with 18 or 23-degree cylinder heads. This gasket is a solid choice for rebuilding or upgrading your engine, especially if you're pushing more power than stock.
Cometic uses multiple layers of stainless steel for strength and corrosion resistance, which also helps the gasket rebound and maintain its seal. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes on both aluminum and cast iron blocks. Because it's an MLS gasket, it doesn't require any additional sealants, making installation more straightforward.
This gasket fits a wide range of vehicles from the late 70s and early 80s, including popular models like the Chevrolet C10, Camaro, and Corvette, as well as GMC trucks. It's a well-built component designed for reliable sealing in performance applications.
