Cometic Ford 289/302/351 4.030 inch Bore .066 inch MLS-5 Head Gasket (Non SVO)

Starting with a multi-layer steel (MLS) construction, this Cometic head gasket uses multiple embossed layers of stainless steel. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, making it suitable for demanding sealing environments and various surface finishes. This gasket is designed for a 4.030 inch bore and has a compressed operating thickness of 0.066 inches.

MLS head gaskets are a solid choice for high-output engines because their layered stainless steel design offers increased strength and the ability to rebound, which helps resist corrosion. They are also well-suited for applications combining aluminum heads with either aluminum or cast iron blocks, as they can handle the shearing forces that can occur between dissimilar materials. Because they are built to seal effectively on their own, these gaskets do not require any additional sealants.

This Cometic gasket fits a wide range of Ford Windsor V8 engines, including popular models like the Ford Bronco, Ford F-150, and AC Shelby Cobra. It's a non-SVO part, meaning it's intended for aftermarket use rather than original equipment replacement in specific SVO applications.
