Cometic MLS head gasket for Ford small-block V8 with AFR heads (4.030" bore) combines embossed Viton-coated stainless outer layers with an uncoated center shim for a compressed thickness of 0.051". Intended for AFR heads with coolant eyebrow, it provides a seal without sealants for aluminum head-to-block interfaces. The multilayer steel construction resists shearing and corrosion while conforming load distribution to limit bore distortion under clamp load.
