Cometic MLS head gasket for Ford small-block V8 with AFR heads (4.080" bore) uses embossed Viton-coated stainless outer layers plus an uncoated center shim for a compressed thickness of 0.051". Specified for AFR heads with coolant eyebrow, it seals aluminum-to-aluminum head/block joints without sealants. The multilayer steel design withstands shearing, resists corrosion, and helps distribute clamp forces to limit bore distortion under load.
