The Cometic MLS head gasket for Ford 385-series 4.400" bore engines is a multi-layer steel cylinder head gasket with a compressed operating thickness of 0.045". Embossed outer stainless layers are coated with heat‑resistant Viton to resist corrosion and harsh sealing environments, while an uncoated center shim lets thickness be varied. MLS construction provides strong rebound and sealing for aluminum-to-aluminum or aluminum-to-cast-iron mating surfaces without sealants.
