Cometic 05+ Ford 4.6L 3 Valve RHS 94mm Bore .027 inch MLS Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring an outer coating of Viton rubber. This construction is designed to handle the high output demands of modern engines, offering maximum sealing performance without needing additional sealants. It's a solid choice whether you're pairing aluminum heads with an aluminum block or aluminum heads with a cast iron block, as it can effectively manage the shearing forces that can occur between dissimilar metals.

The stainless steel layers provide increased strength and resilience, helping the gasket rebound and resist corrosion. The Viton coating on the outer layers is a heat-resistant material, capable of withstanding temperatures up to 482 degrees Fahrenheit (250 C), making it suitable for harsh sealing environments and various surface finishes. The center shim layer is uncoated stainless steel, allowing for adjustments in thickness to meet specific requirements. This particular gasket has a 94mm bore and a compressed operating thickness of 0.098 inches, with a specified thickness of 0.027 inches.
