What is the compressed thickness of this head gasket?

This Cometic Multi-Layer Steel (MLS) head gasket has a compressed operating thickness of 0.060 inches. This measurement is critical for ensuring proper cylinder head seating and compression ratios.

Does this gasket require any sealant?

About this part

Product Details

This is the right-side Multi-Layer Steel (MLS) head gasket from Cometic, specifically made for GM and Mercury 8.1L 496ci big-block V8 engines. It features a compressed thickness of 0.060 inches and a bore size of 4.280 inches, designed to seal the combustion chamber effectively in high-output applications.

Cometic builds these gaskets with 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 them suitable for both aluminum-to-aluminum and aluminum-to-cast iron block configurations. Because they are MLS, they don't require any additional sealants, simplifying installation.

This gasket is intended for a range of GM and Mercury trucks and SUVs, including models like the Chevrolet Silverado 2500 HD and GMC Yukon XL 2500 from 2001 through 2007. It's a well-built component for rebuilding or repairing the top end of these powerful engines.
