Product Details
If you're rebuilding the top end of your Ford Windsor V8 engine, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice. It's designed for a 4.200 inch bore and has a compressed thickness of .056 inches, fitting a wide range of classic Ford vehicles like the Bronco, F-Series trucks, and even some De Tomaso models.
Cometic builds these gaskets with multiple layers of stainless steel, which gives them the strength to handle the demands of high-output engines and resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that ensures a strong seal against both aluminum and cast iron blocks without needing any extra sealants. This construction helps prevent leaks and ensures consistent performance.
This gasket is specifically for non-SVO applications, so double-check your engine build to make sure it's the right fit for your project.
