Cometic MLS head gasket for Ford small-block V8 with AFR heads (4.080" bore) uses embossed stainless outer layers coated with Viton and an uncoated shim layer for a compressed thickness of 0.075". Specified for AFR heads with coolant eyebrow, it seals aluminum head-to-block joints without sealants. The MLS construction resists shearing, rebounds to resist corrosion, and evens clamp load distribution to reduce bore distortion under heavy clamp.
