Cometic Chevy Small Block 4.060 inch Bore .080 inch MLS-5 Head Gasket (18 or 23 Deg. Heads)

If you're rebuilding the top end of your Chevy Gen-1 Small Block V8, getting the head gaskets right is crucial for sealing combustion pressure. This Cometic MLS gasket is built for engines with a 4.060 inch bore and is designed to work with either 18 or 23-degree cylinder heads.

Cometic's Multi-Layer Steel (MLS) gaskets are a solid choice for high-output engines because they're made from multiple layers of stainless steel. This construction gives them strength and the ability to rebound, resisting corrosion and shearing forces, especially when mating aluminum heads to cast iron blocks. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and surface finishes, and the compressed thickness is .080 inches. These gaskets don't require any additional sealants, making installation straightforward.

This gasket fits a wide range of vehicles from the early 80s, including models like the Chevrolet Camaro, GMC C1500, and Buick Regal. It's a well-built component designed to handle the demands of a performance engine build.
