About this part

Product Details

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. If you're working on a 1969-1971 DeTomaso Mangusta, Ford Mustang, or Mercury Cougar with a Ford Boss 302 engine, this gasket is designed to provide a strong seal between your cylinder head and block.

This gasket uses multiple layers of stainless steel for 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°F (250°C). This combination helps ensure a reliable seal, even under the demands of high-output engines, and it doesn't require any additional sealants. The center layer is stainless steel and can be varied in thickness to achieve different compressed operating thicknesses, with this particular gasket measuring 0.040 inches when compressed.
