These Clevite H series bearings are meant for the Forged I and H beam connecting rods offered here on WOT-Tech. 60V6 bearing tangs will not line up properly with the SBC tangs used.
Clevite H-Series rod bearings were primarily developed for NASCAR racing, but are well suited to other types of competition engines. They're especially good for engines that run at medium-to-high revs. They have hardened-steel backings with thin overlays and a high crush factor, plus a medium level of eccentricity. H-Series bearings have enlarged chamfers at the sides for greater crank-fillet clearance and are made without flash plating for better seating
