Cometic Ford SB 4.080 inch Bore .062 inch MLS-5 Head Gasket (w/AFR Heads)

This is a Cometic MLS-5 head gasket, designed for Ford SB engines with a 4.080 inch bore and specifically for use with AFR cylinder heads. It has a compressed thickness of .062 inches. This gasket is built to handle the demands of high-output engines, offering a robust seal without the need for additional sealants. It's well-suited for applications pairing aluminum heads with either aluminum or cast iron blocks, as the multi-layer steel construction can manage the shearing forces between different metals.

The gasket is constructed from multiple layers of stainless steel, which provides increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material rated up to 482 degrees Fahrenheit, ensuring a reliable seal even in harsh conditions and across various surface finishes. The center layer is uncoated stainless steel and can be varied to achieve different gasket thicknesses, like the .062 inch specification on this particular gasket. This design helps ensure maximum sealing performance for your engine build.

This gasket fits a wide range of vehicles, including classic muscle cars and trucks. It's a solid option when rebuilding or upgrading your engine, especially when using performance cylinder heads like those from AFR.
