About this part

Product Details

If you're rebuilding the top end of your 1969-1971 DeTomaso Mangusta, especially with a Ford Boss 302 engine, a reliable head gasket is crucial. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, ensuring a solid seal between your cylinder head and block.

Cometic's MLS design 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) and works well with different block and head materials, including aluminum and cast iron. This construction means you don't need to use additional sealants, and it's designed to withstand the forces created by dissimilar metals. The center layer is stainless steel, and its thickness can be varied to achieve the desired compressed operating thickness, which is 0.036 inches for this specific gasket.

This gasket is specifically made for a 4.155-inch bore and is intended for use with SVO heads and the M-6010-BOSS302 block, making it a direct fit for your Boss 302 application.
