Cometic GM/Mercury 8.1L 496ci 4.280in .051 inch MLS Head Gasket - LH

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. This design is intended for high-output engines and is suitable for mating aluminum heads to either aluminum or cast iron blocks, as it can handle the shearing forces that arise from dissimilar materials. The compressed operating thickness measures 0.051 inches, and this particular gasket is for the Left Hand (LH) side of the engine.

The strength of MLS gaskets comes from their layered stainless steel construction, which allows them to rebound and resist corrosion. The Viton coating on the outer layers is a heat-resistant material capable of withstanding temperatures up to 482 degrees Fahrenheit, making it well-suited for demanding sealing environments. The center shim layer is uncoated stainless steel and can be varied to achieve different thickness requirements, offering flexibility in engine builds. These gaskets do not require additional sealants, simplifying the installation process.

This gasket fits a range of GM and Mercury vehicles, including models like the Chevrolet Suburban 2500 and GMC Sierra 2500 HD. It's a solid option when you need reliable sealing for your 8.1L 496ci engine.
