Cometic GM Gen-V/VI Big Block V8 .089in MLS Cylinder Head Gasket - 4.540in Bore

When you're rebuilding the top end of your GM Gen-V or Gen-VI big block V8, getting the cylinder head gasket right is crucial for a strong seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these powerful engines. It's designed to provide a reliable seal between your cylinder heads and the engine block, helping to keep combustion pressures contained and coolant and oil where they belong.

Cometic uses 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, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron head and block combinations. With a compressed thickness of .089 inches and a 4.540-inch bore, this gasket is engineered for specific big block V8 applications. These gaskets don't require any additional sealants, simplifying installation.

This gasket fits a range of GM trucks and vans from the early 90s through 2000, including popular models like the GMC K2500 and Chevrolet C3500. Ensure you have the correct bore size and thickness for your specific engine build.
