Cometic GM Gen-V/VI Big Block V8 .027in MLS Cylinder Head Gasket - 4.630in 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 MLS (Multi-Layer Steel) head gasket is built to handle the demands of high-output engines, ensuring a reliable seal between your cylinder heads and block without needing any extra sealants.

Cometic uses multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This construction is ideal whether you're mating aluminum heads to an aluminum block or aluminum heads to cast iron. The center layer is uncoated stainless steel, and the compressed thickness on this particular gasket is 0.027 inches, with a 4.630-inch bore diameter, making it suitable for a range of GM Big Block V8 applications from the early 90s.

This gasket fits a variety of Chevrolet and GMC trucks and vans from the early to mid-90s, like the C1500, C2500 Suburban, and K3500. Make sure to check the full fitment list to confirm it's the right part for your specific vehicle.
