Cometic GM Gen-V/VI Big Block V8 .035in 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 gasket right is crucial for a solid seal. This Cometic Multi-Layer Steel (MLS) head gasket is built to handle the demands of high-output engines, offering a reliable barrier between your cylinder head and block.

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 temperatures up to 482 degrees Fahrenheit and works well in tough sealing conditions. This construction means the gasket can handle the differences between aluminum and cast iron blocks and heads without issue, and it doesn't require any additional sealants for installation. The compressed thickness is .035 inches, and the bore size is 4.375 inches, designed for a precise fit on a range of GM Big Block V8 applications, including models like the Chevrolet C1500 and GMC K2500.
