Cometic Chevrolet Mark-IV Big Block V8 .120in MLS Cylinder Head Gasket - 4.375in 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 with a 4.375-inch bore, featuring a compressed thickness of .120 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, as it can manage the shearing forces between different metals.

The construction uses multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, making it suitable for tough sealing jobs. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying installation. This gasket fits a wide range of Chevrolet vehicles, including models like the 1965-1975 Chevrolet Bel Air, 1967-1972 Chevrolet Camaro, and 1965-1974 Chevrolet Corvette.
