Cometic’s MLS head gasket for GM LSX engines is specified for a 4.085" bore and .051" thickness for the left-side bank. Built from multiple embossed AMP-coated and uncoated stainless steel layers, the gasket’s design meets harsh sealing demands and accommodates varied surface finishes. The uncoated stainless shim layer allows thickness variation while requiring less clamp load and improving sealing load distribution.
