Cometic 2004+ Ford 5.4L 3 Valve RHS 94MM .040 inch MLS Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring an outer layer coated with Viton rubber. The compressed operating thickness is precisely 0.040 inches, and this particular gasket is for the Right Side (RHS) of the engine. MLS head gaskets are a solid choice for high-output engines because they don't require any additional sealants and are designed to handle the stresses between different block and head materials, like aluminum to aluminum or aluminum to cast iron. The multiple stainless steel layers provide increased strength and the ability to rebound, while also resisting corrosion. The Viton coating on the outer layers is a heat-resistant elastomer, capable of withstanding temperatures up to 482 degrees Fahrenheit, making it suitable for demanding sealing environments and various surface finishes.

The center layer of this gasket is uncoated stainless steel, and its thickness can be adjusted to meet different requirements, which is how Cometic achieves the 0.040 inch compressed thickness for this specific application. This gasket fits a range of Ford and Lincoln vehicles, including models like the Ford Expedition, F-150, and Lincoln Navigator, making it a versatile option for engine work on these platforms.
