Cometic Ford SB 4.200 inch Bore .060 inch MLS-5 Head Gasket (w/AFR Heads)

If you're working on a Ford SB engine that's been upgraded with AFR heads, this Cometic MLS-5 head gasket is built to seal it up right. It's specifically designed for a 4.200 inch bore and has a compressed thickness of 0.060 inches, with coolant eyebrows designed to work with AFR cylinder heads. This gasket fits a wide range of Ford vehicles, from classic Broncos and F-Series trucks to Explorers and Econoline vans.

Cometic uses a multi-layer steel (MLS) design for these gaskets, which gives them increased strength and the ability to rebound, helping them resist corrosion and withstand the forces in high-output engines. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This construction means you don't need any extra sealants; the gasket is ready to go right out of the box, making it a solid choice for both aluminum-to-aluminum and aluminum-to-cast iron head and block combinations.
