Cometic GM Gen-V/VI Big Block V8 .045in MLS Cylinder Head Gasket - 4.320in Bore

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for GM Gen-V/VI Big Block V8 engines. It features a 4.320-inch bore and a compressed thickness of 0.045 inches, making it suitable for a wide range of Chevrolet and GMC trucks and vans from the early 90s through the late 90s, like the Chevrolet C1500 or GMC K2500 Suburban.

Cometic builds these gaskets 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 tough sealing environments and various surface finishes, ensuring a solid seal without needing additional sealants. This construction is ideal for engines using aluminum heads with either aluminum or cast iron blocks, as it can manage the stresses between different metals.
