Cometic MLS head gasket for Dodge V8 351 (4.23in bore, .040in thickness) uses multiple embossed layers combining AMP coating and uncoated stainless steel to meet demanding sealing environments. The embossed outer layers conform to surface finishes, the central shim layer allows thickness variation, and the MLS design requires less clamp load while distributing sealing forces to minimize bore distortion under high clamp and thermal stress.
