The Cometic MLS head gasket for Honda CB500 (1972–1982) fits a 61mm bore at .040" thickness and is built for reliable head sealing during rebuilds. Its multi-layer steel construction uses embossed AMP-coated outer layers plus an uncoated stainless center shim to tolerate varied surface finishes and load conditions. The center layer can be varied for thickness, needs less clamp load to reduce bore distortion, and evens out load distribution across the sealing surface.
