Cometic Ford 2.3L 4CYL 3.94in Bore .040 inch MLS Head Gasket

This is a Cometic Multi-Layer Steel (MLS) head gasket specifically made for Ford 2.3L 4-cylinder engines with a 3.94-inch bore. It's built with multiple layers of stainless steel, and the outer layers have a heat-resistant Viton rubber coating. This gasket is designed to provide a strong seal for high-output engines and fits a range of Ford and Mercury vehicles, including models like the Ford Mustang, Aerostar, and Mercury Bobcat. It's suitable for use with both aluminum and cast iron blocks.

The multi-layer steel construction gives this gasket increased strength and the ability to rebound, helping it resist corrosion and withstand the forces created when mating different metals like aluminum heads to cast iron blocks. The Viton coating on the outer layers is rated for temperatures up to 482°F (250°C), making it well-suited for demanding sealing environments. The center layer is uncoated stainless steel and can be varied in thickness to meet specific requirements; in this case, it's set to a compressed operating thickness of 0.040 inches. These gaskets are designed to seal effectively without the need for additional sealants.
