Cometic Ford SB 4.080 inch Bore .027 inch MLS Head Gasket (w/AFR Heads)

If you're working on a Ford Windsor V8 engine, especially one fitted with AFR heads, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice. It's designed with a specific 4.080 inch bore and a compressed thickness of 0.027 inches, ensuring a precise fit for these applications. This gasket is built to handle the demands of high-output engines, providing a reliable seal without needing any additional sealants.

Cometic's MLS design uses multiple layers of stainless steel, which not only increases strength but also allows the gasket to rebound and resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This construction makes it suitable for sealing aluminum heads to either aluminum or cast iron blocks, as it can manage the shearing forces that can occur between different metals. The center layer is also stainless steel, and its thickness can be varied to meet different requirements, like the 0.027 inch specification on this particular gasket.

This gasket fits a wide range of vehicles, including classic Ford trucks and Broncos, as well as many GM and even some Mopar models from the 70s and 80s. It's a well-built component designed for performance and durability.
