Cometic MLS .060" MLX head gasket for Ford Windsor V8 (4.200" bore) uses multiple embossed stainless steel layers with Viton-coated outer faces and a compressed operating thickness of 0.036". The MLS construction provides corrosion resistance and rebound under load, and the gaskets include an integrated stopper layer for combustion sealing, making them suitable for aluminum-to-aluminum and aluminum-to-iron head/block combinations without the need for sealants.
