Cometic Ford SB 4.100 inch Bore .060 inch MLS-5 Head Gasket (w/AFR Heads)

If you're rebuilding the top end of a Ford SB engine, especially one fitted with AFR heads, this Cometic MLS-5 head gasket is a solid choice. It's designed with a 4.100 inch bore and a compressed thickness of 0.060 inches, specifically accounting for the coolant eyebrow found on many AFR cylinder heads. This gasket is built for high-output engines and is suitable for both aluminum-to-aluminum and aluminum-to-cast iron block configurations.

Cometic's Multi-Layer Steel (MLS) construction uses 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, allowing for precise thickness control. These gaskets don't require any additional sealants, making installation more straightforward.

This gasket fits a wide range of Ford vehicles and engine applications, from classic Broncos and F-Series trucks to later model Explorers. It's a well-built component designed to provide reliable sealing under demanding conditions.
