Cometic GM Gen-V/VI Big Block V8 .036in MLS Cylinder Head Gasket - 4.320in 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 sealing combustion pressure and coolant. This Cometic Multi-Layer Steel (MLS) gasket is built to handle the demands of high-output engines, offering a reliable seal between your cylinder heads and engine block.

This gasket is constructed with multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This construction makes it suitable for use with both aluminum and cast iron blocks, and it doesn't require any additional sealants, simplifying installation. The compressed thickness is .036 inches, and it's designed for a 4.320-inch bore, fitting a wide range of GM trucks and vans from the early 90s, like the Chevrolet C1500 and GMC K2500.
