Cometic Twin Cam MLS head and base kit uses multiple embossed layers of AMP coating and uncoated stainless steel with a center shim layer to meet demanding sealing environments. The MLS construction conforms load distribution, requires less clamp load to reduce bore distortion, and is intended for Twin Cam air-cooled applications where consistent head sealing and thickness options are important.
