Product Details

Starting with a compressed operating thickness of 0.040 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious Ford Windsor V8 engines. It's designed to handle the demands of high-output applications, offering a strong seal without needing additional sealants. This makes it a solid choice whether you're pairing aluminum heads with an aluminum block or with cast iron.

The construction uses multiple layers of stainless steel, which not only adds strength but also allows the gasket to rebound and resist 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 and various sealing challenges. The center layer is uncoated stainless steel, and its thickness can be adjusted to meet different requirements, giving you a well-built gasket that fits right.

This gasket is suitable for a wide range of Ford vehicles, including models like the Ford Bronco, Ford E-Series vans, and classic AC Shelby Cobras. It's a popular option for engine rebuilds where a reliable seal is critical.
