Product Details

If you're working on a Chevrolet Mark-IV Big Block V8 and need a reliable head gasket, this Cometic Multi-Layer Steel (MLS) gasket is a solid choice. It's built with multiple layers of stainless steel, giving it the strength to handle the demands of high-output engines. This gasket is designed for a 4.375-inch bore and has a compressed thickness of 0.045 inches, making it suitable for a wide range of applications, including vehicles like the Chevrolet Impala, Camaro, and Corvette from the mid-60s to the mid-70s, as well as many C/K series trucks.

What sets this gasket apart is its construction. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating, combined with the embossed stainless steel layers, ensures a strong seal without needing any additional sealants. Whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, these MLS gaskets are designed to withstand the forces involved and resist corrosion, providing a durable seal for your engine rebuild.
