This Cometic MLS head gasket is specified for Chevrolet Mark‑IV Big Block V8 with a 4.610" bore and .060" thickness, built from multiple embossed layers combining AMP coating and uncoated stainless steel. The embossed outer layers meet harsh sealing demands while the uncoated stainless shim layer allows precise thickness control. The multilayer design conforms load distribution across the sealing area and requires less clamp load to help reduce bore distortion.
