Cometic MLS head gasket for Ford small-block V8 with AFR heads (4.155" bore) uses embossed stainless outer layers coated with Viton and an uncoated shim for a compressed thickness of 0.030". Designed for AFR heads with coolant eyebrow, it seals aluminum interfaces without sealants. The multilayer steel construction resists shearing, rebounds to resist corrosion, and evens clamp load to reduce bore distortion in performance applications.
