Cometic Chevrolet Mark-IV Big Block V8 .062in MLS Cylinder Head Gasket - 4.375in Bore

If you're working on a Chevrolet Mark-IV Big Block V8, this Cometic Multi-Layer Steel (MLS) head gasket is a solid option for sealing your cylinder heads. It's designed with a compressed thickness of .062 inches and a bore size of 4.375 inches, making it suitable for a wide range of applications including the Chevrolet Bel Air, Impala, and Corvette from the mid-60s to mid-70s, as well as many GM trucks and vans from that era.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a reliable seal even in demanding conditions. Because it's an MLS gasket, it doesn't require any additional sealants, and it's designed to handle the forces created when mating aluminum heads to either aluminum or cast iron blocks. The center layer is uncoated stainless steel, and its thickness can be varied to meet different engine build requirements.
