Cometic Chevy Gen1 Small Block V8 .080in MLS Cylinder Head Gasket - 4.060in Bore

When you're rebuilding the top end of your Chevy Gen-1 Small Block V8, a good head gasket is crucial for sealing the combustion chamber and coolant passages. This Cometic MLS (Multi-Layer Steel) gasket is designed for a 4.060-inch bore and has a thickness of .080 inches, making it suitable for a range of applications including many Chevrolet, Buick, and GMC trucks and cars from the early 80s.

Cometic builds these gaskets with three to five layers of stainless steel. They use stainless steel because it's strong, resists corrosion, and can rebound well to maintain a tight seal. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F and works well in tough sealing environments and on various surface finishes. This construction helps ensure a reliable seal under demanding conditions.
