This Cometic MLS head gasket for Porsche 997 3.6L (102mm bore) uses multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated shim layer to provide resilient, corrosion-resistant sealing. Compressed operating thickness is specified and the MLS design avoids sealants while handling differing head/block materials and high output demands. The integrated stopper layer helps ensure combustion sealing reliability.
