About this part

Product Details

This is a Cometic Multi-Layer Steel (MLS) head gasket, specifically designed for the Ford Boss 302 engine. You get one gasket, measuring .066 inches thick with a 4.155-inch bore, ready to seal your cylinder heads to the block. It's built to handle the demands of high-output engines without needing any extra sealants.

Cometic uses multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing jobs and different surface finishes. This construction is ideal whether you're mating aluminum heads to an aluminum block or aluminum heads to a cast iron block, as it can manage the stresses between dissimilar metals. The center layer is stainless steel, and the overall thickness is set at .066 inches when compressed.
