Cometic's MLS head gasket for GM LS Gen-3/4 small block V8s (4.190" bore, .120" thickness) employs HP shim technology to increase clamp load around the combustion chamber for improved sealability on open-deck blocks. Built from multiple embossed stainless steel layers with AMP coating, the gasket manages clamp load, conforms sealing area distribution and resists distortion under high loads.
