Cometic Chevy Gen-1 Small Block V8 .023in MLS Cylinder Head Gasket - 4.100in Bore - Round Bore

This is a Cometic Multi-Layer Steel (MLS) head gasket designed for Chevrolet Gen-1 Small Block V8 engines. It features a 4.100-inch bore and a round bore design, making it suitable for a wide range of GM vehicles from the 1980s and 1990s, including models like the Chevrolet Camaro, Corvette, and GMC C1500.

MLS head gaskets are built with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle demanding sealing environments and various surface finishes. This construction means the gasket seals effectively without needing additional sealants, and it's well-suited for combinations of aluminum and cast iron engine blocks and heads, as it can manage the shearing forces between different metals. The compressed operating thickness is 0.036 inches.
