Cometic Ford SB 4.200 inch Bore .051 inch MLS Head Gasket (w/AFR Heads)

Starting with a compressed thickness of 0.051 inches, this Multi-Layer Steel (MLS) head gasket from Cometic is built for demanding Ford SB applications, especially when paired with AFR heads that feature a coolant eyebrow. The multi-layer stainless steel construction provides increased strength and the ability to rebound, which helps resist corrosion and withstand the shearing forces between aluminum and cast iron blocks. This well-built design means you don't need additional sealants for a reliable seal.

The outer layers of this gasket are embossed and coated on both sides with Viton, a heat-resistant rubber material rated up to 482°F (250°C). Viton is chosen for its ability to handle harsh sealing environments, varying load conditions, and different surface finishes, ensuring a dependable seal over time. The center layer is uncoated stainless steel, allowing for precise thickness control to meet specific engine build requirements. This gasket is a solid option for high-output engines and fits a range of Ford vehicles, including the Bronco, F-100, and Explorer models.
