Cometic Ford SB 4.080 inch Bore .060 inch MLS-5 Head Gasket (w/AFR Heads)

Cometic Gasket is well-known for making robust sealing solutions, especially their multi-layer steel (MLS) head gaskets. This particular MLS-5 gasket is built for Ford SB engines when using AFR heads, featuring a 4.080 inch bore and a compressed thickness of 0.060 inches. It's designed to handle the demands of high output engines, offering maximum sealing performance without needing any additional sealants.

The construction uses multiple layers of stainless steel, which gives it strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes. This design is effective for sealing aluminum heads to either aluminum or cast iron blocks, as it can manage the shearing forces that occur between these materials. The center layer is also stainless steel and can be varied to achieve different gasket thicknesses, like the 0.060 inch specification on this part.

This gasket fits a wide range of vehicles, including classic muscle cars and trucks like the Ford Bronco, Chevrolet Camaro, and AC Shelby Cobra. It's a solid option if you're rebuilding the top end of your engine and need a reliable seal for performance applications.
