The Cometic MLS head gasket for Ford FE V8 applications pairs embossed stainless steel outer layers coated with Viton and a market-compressed thickness of 0.036" with a 4.080" bore. It does not fit the 427 SOHC Cammer. The center shim is uncoated stainless for thickness variation while MLS construction reduces clamp load, distributes sealing forces evenly and resists corrosion to improve long-term cylinder sealing.
