Cometic 94-03 Ford 7.3L Power Stroke .080in MLS Cylinder 4.140in Bore VIN F Head Gasket

The multi-layer steel (MLS) construction of this Cometic head gasket, featuring embossed outer layers coated with Viton, is designed to handle the high output demands of engines like the Ford 7.3L Power Stroke. This gasket has a compressed operating thickness of 0.036 inches and a bore size of 4.140 inches, making it suitable for specific engine builds from 1994 to 2003, particularly those with VIN F designations.

MLS gaskets are built with multiple layers of stainless steel, which not only increases their strength but also allows them 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 is designed to seal effectively in harsh environments and on various surface finishes. The center layer is uncoated stainless steel, and Cometic uses these shim layers to achieve precise thickness requirements, like the 0.080 inches specified for this gasket. These gaskets are well-suited for applications with aluminum heads on either aluminum or cast iron blocks, as they can manage the shearing forces that can occur between different metal types.

This gasket is a solid option for rebuilding the top end of your Ford 7.3L Power Stroke engine. Because they are designed for maximum sealing performance, Cometic MLS head gaskets do not require additional sealants, simplifying the installation process. This part fits a range of Ford trucks and vans, including models like the F-250 Super Duty, E-350 Econoline, and Excursion.
