Product Details
If you're rebuilding the top end of a Chevy Small Block V8, this Cometic Multi-Layer Steel (MLS) head gasket is a solid option. It's designed for a 4.200 inch bore and has a compressed thickness of .027 inches, with all steam holes included to help manage heat. This gasket fits a wide range of vehicles from the early 80s, including models like the Chevrolet C10, Camaro, and GMC C1500.
Cometic builds these MLS gaskets with multiple layers of stainless steel, which gives them 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 different surface finishes, making them suitable for use with both aluminum and cast iron blocks. Because they're MLS, they don't require any additional sealants, simplifying installation.
