Cometic GM Gen-V/VI Big Block V8 .060in MLS Cylinder Head Gasket - 4.540in Bore

Starting with the Viton rubber coating on the outer layers, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the heat and pressure of GM Gen-V/VI Big Block V8 engines. The compressed thickness is a precise 0.060 inches, and the bore size is 4.540 inches, making it a solid choice for a range of these powerful V8s, including many Chevrolet and GMC trucks from the early 90s through the late 90s and early 2000s.

The multi-layer steel construction offers increased strength and resilience, allowing the gasket to rebound and resist corrosion, which is crucial when mating aluminum heads to either aluminum or cast iron blocks. This design means you don't need additional sealants; the gasket itself provides maximum sealing performance for high-output applications. The Viton coating is heat resistant up to 482 degrees Fahrenheit, ensuring it can stand up to demanding sealing environments and various surface finishes.
