Cometic Chevrolet Mark-IV - GM Gen-V/VI Big Block V8 .095in MLS Cylinder Head Gasket - 4.570in Bore

Starting with a compressed operating thickness of 0.095 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious performance. It's constructed from multiple layers of stainless steel, giving it the strength to handle the demands of high-output engines. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a solid seal even in harsh conditions. This makes it a great choice for sealing aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as it can manage the different expansion rates between these materials.

The center layer is stainless steel and can be varied to achieve different thicknesses, which is how Cometic offers this gasket in the 0.095-inch compressed size. This particular gasket is designed for aftermarket heads and features undersized water ports, allowing you to customize them to your specific setup. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying the installation process. It's well-suited for applications like Brodix Big Duke and Brodie heads.

This gasket fits a wide range of Chevrolet and GM vehicles from the 1960s through the 1990s, including popular models like the Chevrolet Impala, C10 Pickup, and Camaro. It's a solid option when you need reliable sealing for your big block V8 build.
