Cometic Ford SB 4.100 inch Bore .045 inch MLS Head Gasket (w/AFR Heads)

This Multi-Layer Steel (MLS) head gasket from Cometic is built with embossed stainless steel layers, featuring an outer coating of Viton rubber. This specific gasket has a compressed thickness of 0.045 inches and is designed to work with AFR heads that have a coolant eyebrow. It's engineered to provide maximum sealing performance for high-output engines, and it doesn't require any additional sealants.

MLS gaskets are a solid choice for engines with aluminum heads paired to either aluminum or cast iron blocks, as they can handle the shearing forces that arise from dissimilar metals. The multiple stainless steel layers give these gaskets increased strength and the ability to rebound, while also resisting corrosion. The Viton coating on the outer layers is a heat-resistant elastomer, capable of withstanding temperatures up to 482°F (250°C) and meeting the demands of harsh sealing environments and various surface finishes. The center layer is uncoated stainless steel and can be varied in thickness to meet different sealing requirements.

This gasket fits a wide range of Ford Windsor V8 engines, including models like the Ford Bronco, Ford E-Series vans, and AC Shelby Cobras, among many others. It's a well-built component for rebuilding or upgrading your engine's top end.
