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 0.050" compressed thickness for a 4.380" bore, it seals aluminum-to-aluminum and aluminum-to-cast-iron interfaces without sealants while resisting heat and corrosion. The layered design rebounds under load, evens clamp load across the sealing area, and helps reduce bore distortion in high-output engines.
