Cometic MLS head gasket for Ford small-block V8 with AFR heads (4.100" bore) combines embossed stainless outer layers coated with Viton and an uncoated center shim for a compressed thickness of 0.040". With coolant eyebrow for AFR heads, it seals aluminum head/block interfaces without sealants. The multilayer steel construction resists shearing and corrosion, rebounds under load, and helps distribute clamp load to reduce bore distortion in performance builds.
