Cometic Ford FR 427 SOHC 4.400in Bore .080in MLS-5 Head Gasket

If you're rebuilding the top end of a Ford 427 SOHC engine, getting the sealing right is crucial, especially with high-output builds. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle those demands. It's designed to provide a solid seal between your cylinder head and block, ensuring proper compression and preventing coolant and oil leaks.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. 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 advanced coating helps create a reliable seal even on varied surface finishes and under tough load conditions. The center layer is stainless steel and its thickness is varied to achieve the specific 0.080 inch compressed operating thickness needed for this application, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron block combinations.

This gasket fits a wide range of classic Ford and Mercury vehicles from the 1960s, including models like the Ford Fairlane, Mercury Cyclone, and AC Shelby Cobra. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying the installation process.
