The Cometic MLS head gasket for Ford 302/351W Windsor V8 is a multi-layer stainless steel cylinder head gasket with a 4.030" bore and .140" compressed operating thickness. Embossed outer layers are coated both sides with Viton to resist heat to 250°C (482°F). MLS construction copes with mixed-material shearing, requires no sealants, and uses an uncoated center shim to allow thickness variation while reducing clamp load and improving sealing load distribution.
