Cometic Ford 289/302/351 4.200 inch Bore .030 inch MLS Head Gasket (Non SVO)

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring an outer coating of Viton rubber. The compressed operating thickness is precisely 0.030 inches. These gaskets are designed to provide maximum sealing performance for today's high-output engines, and they don't require any additional sealants. They work well with both aluminum-to-aluminum head and block combinations, as well as aluminum heads on cast iron blocks, because they can handle the shearing forces that can occur between different metals.

The strength of MLS gaskets comes from their multiple stainless steel layers, which also allow them to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton, a heat-resistant rubber material capable of handling temperatures up to 482 degrees Fahrenheit. Viton is chosen for its ability to perform in demanding sealing environments and under various load conditions. The center layer is uncoated stainless steel and can be varied to achieve different thickness requirements.

This gasket fits a wide range of Ford Windsor V8 engines, including popular models like the Ford Bronco, Ford F-Series trucks, and AC Shelby Cobras from various years. It's a solid option when rebuilding or refreshing the top end of these classic V8s.
