Cometic GM Gen-V/VI Big Block V8 .050in 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 gaskets right is crucial for a solid seal. This Cometic Multi-Layer Steel (MLS) gasket is built for engines with a 4.375-inch bore and a compressed thickness of 0.050 inches, designed to handle the demands of high-output applications.

These MLS gaskets are constructed from multiple layers of stainless steel, which gives them rebound ability 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, meaning you don't need extra sealants. This construction is ideal whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as it can manage the shearing forces between different metals.

This gasket fits a wide range of GM trucks and vans from the early 90s through the early 2000s, including popular models like the Chevrolet C1500 and GMC C3500. Ensure you have the correct bore size and compressed thickness for your specific engine build.
