Cometic Chevrolet Mark-IV Big Block V8 .120in MLS Cylinder Head Gasket - 4.320in Bore

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. It's designed for Chevrolet Mark IV Big Block V8 engines, featuring a 4.320-inch bore and a compressed thickness of .120 inches. This gasket is built to handle the demands of high-output engines, ensuring a solid seal without needing extra sealants.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle harsh sealing environments and various surface finishes. This makes it suitable for combinations of aluminum heads with aluminum blocks or cast iron blocks, as it can manage the shearing forces that arise from different materials. The center layer is stainless steel, allowing for precise thickness control to meet specific engine requirements.

This gasket fits a wide range of vehicles, including models like the 1965-1975 Chevrolet Bel Air, 1967-1972 Chevrolet Camaro, and 1965-1974 Chevrolet Corvette. It's a solid option for rebuilding or upgrading your engine's top end.
