This Cometic MLS head gasket is specified for GM LSX Gen-4 engines with a 4.185in bore and .051in thickness, manufactured from multiple embossed layers combining AMP (Advanced Multi-Polymer) coating and uncoated stainless steel. The embossed outer layers and uncoated center shim layer improve sealing across challenging conditions, reduce required clamp load and better distribute sealing loads for reliable head sealing.
