The Cometic MLS cylinder head gasket for Chrysler B/RB V8 combines multiple embossed stainless-steel layers with Viton-coated outer faces and an uncoated shim. With a compressed thickness of 0.140" for a 4.350" bore, it seals aluminum-to-aluminum and aluminum-to-cast-iron interfaces without sealants and resists heat and corrosion. The layered construction rebounds under load, copes with shearing between dissimilar metals, and conforms to surface finishes to distribute clamp load and reduce bore distortion.
