Cometic MLS cylinder head gasket for GM LS Gen-3/4 small-block V8, .040in thickness with a 4.035in bore. HP shim technology raises clamp load around the combustion chamber to improve sealing on open-deck blocks. Embossed stainless steel outer layers use AMP coating and Viton on the faces, while a central uncoated shim layer lets thickness be tailored; the design seals under varied flange conditions with less clamp load.
