Cometic Ford SB 4.155 inch Bore .084 inch MLS-5 Head Gasket (w/AFR Heads)

If you're rebuilding the top end of your Ford Windsor V8, especially when using AFR heads, a solid head gasket is crucial for sealing. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines. It's designed to provide a reliable seal without needing any additional sealants, making the installation process more straightforward.

Cometic constructs these gaskets with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well with various surface finishes. The center layer is uncoated stainless steel, and its thickness can be varied to meet different requirements, with this specific gasket having a compressed thickness of 0.084 inches and a bore size of 4.155 inches. This construction makes them suitable for sealing aluminum heads to both aluminum and cast iron blocks, as they can manage the shearing forces that can occur between different metals.

This gasket is a good option for a wide range of Ford vehicles, including models like the Ford Bronco, F-100, and E-Series vans, when equipped with AFR heads. It's designed to fit right and perform reliably in demanding applications.
