About this part

Product Details

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

Cometic uses multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating, along with embossed outer layers, helps create a reliable seal without needing additional sealants, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron block configurations. The center layer is stainless steel and can be varied in thickness; this particular gasket has a compressed operating thickness of .080 inches and a 4.155-inch bore, designed to work with SVO heads and M-6010-BOSS302 blocks.
