The Cometic MLS head gasket for GM LSX (4.150in bore, .044in thickness) is supplied as the left-side gasket and uses multiple embossed layers with AMP coating and uncoated stainless steel. Its embossed outer layers adapt to harsh sealing environments and surface finishes, while the uncoated center shim allows thickness variation. The MLS construction reduces clamp load and evens load distribution.
