Chevrolet Mark-IV Big Block V8 .036in MLS Cylinder Head Gasket 4.630in Bore

Cometic Gasket is well-known for making solid sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s built for Chevrolet Mark IV Big Block V8 engines, offering a 4.630-inch bore and a compressed thickness of 0.036 inches. This gasket is designed to handle the demands of high-output engines, whether you're pairing aluminum heads with aluminum blocks or aluminum heads with cast iron blocks. The multiple layers of stainless steel provide strength and resistance to corrosion, while the outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments.

The construction of this MLS gasket means it doesn't require any additional sealants, simplifying installation. The embossed outer layers with Viton coating are specifically designed to meet the challenges of various sealing conditions, load requirements, and surface finishes. The center layer is uncoated stainless steel, allowing for precise thickness control. This gasket fits a wide range of vehicles, including models like the 1965-1975 Chevrolet Bel Air, 1968-1974 Chevrolet C10 Pickup, and 1967-1972 Chevrolet Camaro.
