Product Details
When you're rebuilding the top end of your Ford 221 Flathead V8, a reliable head gasket is crucial for sealing combustion pressures and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these classic engines, offering a solid option for your project.
This gasket is constructed with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle harsh sealing environments and varying surface finishes, ensuring a tight seal without needing additional sealants. With a compressed operating thickness of 0.120 inches and a bore size of 3.156 inches, it's designed to fit the Ford 221 Flathead V8 engine. MLS gaskets are well-suited for both aluminum and cast iron block applications, as they can manage the shearing forces that can occur between different metals.
This Cometic head gasket fits a wide range of classic Ford and Mercury vehicles from the late 1930s through the mid-1950s, including models like the Ford F-1, Ford Customline, and Mercury Monterey. Ensure you have the correct gasket for your specific build to maintain proper engine compression and cooling.
