The Cometic MLS cylinder head gasket for Chrysler B/RB V8 uses multiple embossed stainless-steel layers with Viton-coated outer faces and a central uncoated shim. At a compressed operating thickness of 0.120" and a 4.350" bore, it seals aluminum-to-aluminum and aluminum-to-cast-iron interfaces without sealants while resisting heat and corrosion. The MLS design rebounds under load, tolerates metal shearing, and evens clamp load to help limit bore distortion in demanding engines.
