Cometic GM Gen-V/VI Big Block V8 .086in MLS Cylinder Head Gasket - 4.320in Bore

This product includes one Cometic Multi-Layer Steel (MLS) cylinder head gasket, designed for GM Gen-V/VI Big Block V8 engines. It features a compressed thickness of .086 inches and a bore size of 4.320 inches. This gasket is built to handle the demands of high-output engines and fits a range of Chevrolet and GMC trucks from the early 90s through the late 90s, including models like the Chevrolet C1500 and GMC K2500 Suburban.

Cometic's MLS gaskets are constructed from multiple layers of stainless steel, which provides increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482 degrees Fahrenheit. This construction makes them suitable for sealing between aluminum heads and either aluminum or cast iron blocks, as they can manage the shearing forces that arise from dissimilar metals. Because they are multi-layer steel, these gaskets don't require any additional sealants for proper installation.
