The Cometic MLS head gasket for Jaguar 3.8L XK6 (89mm bore) is a multi-layer stainless steel cylinder head gasket listed at .086in thickness with a compressed operating spec in manufacturer notes. It provides reliable sealing without sealants for aluminum-to-aluminum or aluminum-to-iron installations. Embossed outer layers are Viton-coated for heat-resistant sealing; the uncoated stainless shim layer supports thickness variation, rebounds under load, evens sealing pressure, and reduces bore distortion.
