Product Details

If you're working on a Chevrolet Gen-1 Small Block V8 engine, this Cometic MLS head gasket is built to handle the job. It's designed for a 4.200 inch bore and has a compressed thickness of 0.070 inches, with all the necessary steam holes included to help manage heat. This gasket fits a wide range of vehicles from the early 80s, including popular models like the Chevrolet C10, Camaro, and GMC C1500.

Cometic's Multi-Layer Steel (MLS) gaskets are a solid choice for high-output engines because they offer excellent sealing without needing any extra sealants. They're constructed from multiple layers of stainless steel, which gives them strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and different surface finishes, making them suitable for use with both aluminum and cast iron blocks.
