Cometic GM Gen-V/VI Big Block V8 .120in MLS Cylinder Head Gasket - 4.630in Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring a Viton rubber coating on the outer layers. With a compressed operating thickness of 0.120 inches and a 4.630-inch bore, it's designed for GM Gen-V/VI Big Block V8 engines. These gaskets are ideal for sealing high-output engines, working well with both aluminum-to-aluminum and aluminum-to-cast iron block configurations, and they don't require additional sealants.

The stainless steel construction offers increased strength and resistance to corrosion, while the Viton coating on the outer layers is a heat-resistant fluoropolymer capable of handling temperatures up to 482°F (250°C). This makes it suitable for demanding sealing environments and various surface finishes. The center shim layer is uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine requirements.

This gasket fits a range of Chevrolet and GMC trucks and vans from the early to mid-1990s, including models like the Chevrolet C1500, GMC C2500 Suburban, and Chevrolet C3500. It's a well-built component for rebuilding or repairing your engine's top end.
