Cometic Ford SB 4.155 inch Bore .030 inch MLS Head Gasket (w/AFR Heads)

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed thickness of 0.030 inches and a 4.155-inch bore, specifically designed for Ford SB engines when using AFR cylinder heads. The MLS construction uses multiple layers of stainless steel, which gives it strength and resistance to corrosion, making it a solid choice for high-output engines. These gaskets are designed to seal effectively without needing any additional sealants, whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as they can handle the different expansion rates between these materials.

The outer layers of this gasket are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. Viton is chosen for its ability to perform in demanding sealing environments and on various surface finishes. The center layer is uncoated stainless steel, and its thickness can be varied to meet different sealing requirements. This updated design helps ensure a reliable seal under the stresses of performance applications.

This gasket fits a wide range of Ford Windsor V8 applications, including popular models like the Ford Bronco and F-100, as well as vehicles such as the AC Shelby Cobra. It's a well-built component for rebuilding or upgrading your engine's top end.
