Cometic Ford FE 352-428 4.400in Bore .086 inch MLS Head Gasket

Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious sealing performance. With a compressed operating thickness of 0.086 inches, it's designed to handle the demands of high-output engines without needing additional sealants. This makes it a solid choice for builds using aluminum heads with either aluminum or cast iron blocks, as the multi-layer steel construction can effectively manage the shearing forces that can occur between dissimilar metals.

The strength of these MLS gaskets comes from their multiple stainless steel layers, which also allow them to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton, a heat-resistant rubber material rated up to 482 degrees Fahrenheit. Viton is chosen for its ability to perform in harsh sealing environments, under various load conditions, and on different surface finishes. The center shim layer is uncoated stainless steel and can be varied to achieve different thickness requirements, like the 0.086 inches found in this specific gasket.

This gasket fits a wide range of Ford FE engines from 1957 through 1976, including popular models like the Ford F-100, F-250, Fairlane, and Galaxie. It's important to note that this gasket does not fit the 427 SOHC Cammer engine. Ensure you check the full fitment list to confirm compatibility with your specific vehicle.
