Cometic Chevy Gen1 Small Block V8 .040in MLS Cyl Head Gasket-4.190in Bore-All Pro Heads-Round Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built for Chevrolet Gen-1 Small Block V8 engines. It's specifically designed with a 4.190-inch bore and a .040-inch thickness, making it a solid choice for rebuilds using All Pro heads with a round bore configuration. This gasket is engineered to work with open deck block designs, a common setup for many classic V8s.

The key to this gasket's performance is its HP shim technology. This feature increases the clamping force around the combustion chamber, which significantly improves the sealability, especially in open deck blocks where sealing can be more challenging. The outer layers of the gasket are embossed and coated with Viton, a material known for its resistance to heat and oil, helping to ensure a long-lasting seal under demanding conditions.

This gasket fits a wide range of Chevrolet and GMC trucks, cars, and vans from the early 1980s, including popular models like the Chevrolet C10 and GMC C1500. It's a well-built component for anyone rebuilding or repairing their Gen-1 Small Block V8.
