Cometic GM Gen-V/VI Big Block V8 .120in MLS Cylinder Head Gasket - 4.375in Bore

When you're rebuilding the top end of your GM Gen-V/VI Big Block V8, getting the cylinder head gaskets right is crucial for a strong seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, ensuring reliable performance without needing extra sealants.

Cometic uses multiple layers of stainless steel for increased strength and corrosion resistance, which also allows the gasket to rebound effectively. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This construction makes it suitable for both aluminum-to-aluminum and aluminum-to-cast iron head and block combinations, as it can manage the shearing forces between different metals. With a compressed operating thickness of 0.120 inches and a 4.375-inch bore, it's designed for specific Big Block V8 applications.

This gasket fits a wide range of GM trucks and vans from the early 90s through the late 90s, including popular models like the Chevrolet C1500 and GMC C3500. It's a well-built component for anyone looking to ensure a solid seal during their engine build.
