Cometic Ford 302/351 106.17mm Round Bore .051in MLS-5 Head Gasket

Starting with a .051 inch compressed thickness and a 4.180 inch bore, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious sealing. It's designed for Ford 302 and 351 Windsor V8 engines, and it's a popular choice for high-output builds where reliable sealing is critical. This gasket is made to handle the demands of modern engines, whether you're pairing aluminum heads with an aluminum block or aluminum heads with cast iron.

The strength of this gasket comes from its multiple layers of stainless steel, which also help it resist corrosion and maintain its shape under stress. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating ensures a solid seal even with different surface finishes and under tough operating conditions. The center layer is uncoated stainless steel, and Cometic can vary this layer to achieve different gasket thicknesses, like the .051 inch on this particular gasket.

This gasket is designed to work without needing any additional sealants, making installation more straightforward. It fits a wide range of Ford vehicles, including popular models like the Bronco, E-Series vans, and F-Series trucks from the late 60s through the mid-90s.
