The Cometic MLS head gasket for BMW M42/M44 engines (86mm bore, .075in compressed thickness) uses multiple embossed stainless steel layers with Viton-coated outer faces to provide high-strength sealing without sealants. The uncoated center shim layer accommodates thickness requirements while the MLS design resists corrosion, helps distribute clamp load, and reduces bore distortion between dissimilar head and block materials.
