Cometic 2004+ Ford 5.4L 3 Valve RHS 94MM .036 inch MLS Head Gasket

This is the right-side head gasket you get from Cometic, designed for the 2004 and later Ford 5.4L 3-valve engine with a 94mm bore. It's a Multi-Layer Steel (MLS) gasket, meaning it's built from several layers of stainless steel for strength and resilience. This construction helps it handle the demands of high-output engines without needing extra sealants, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron block setups.

The outer layers of this gasket are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating is embossed into the stainless steel layers, which helps create a strong seal against the cylinder head and block. The center layer is also stainless steel, and its thickness is what determines the gasket's final compressed operating thickness, which is set at 0.036 inches for this specific part. This design allows the gasket to rebound and resist corrosion, offering a durable sealing solution.
