Cometic’s .030" MLS head gasket for BMW M54B25/M54B30 (85mm bore) is a multi-layer steel gasket built for reliable sealing without sealants. Comprised of embossed stainless-steel layers with Viton-coated outer faces and an uncoated shim center, it resists corrosion, rebounds under load and tolerates dissimilar head/block pairings. The .030" compressed thickness reduces required clamp load and helps control bore distortion.
