Both are correct. The BLOCK is a M10x1.50 thread, where the stud will thread into. The other end of the thread is the M10x1.25, where the NUT will thread onto. Hence the 2 different thread pitches.
BTW, i have installed these and they are absolutely perfect! Zero clearance issues with the oil pan. The ARP rep told me to just use their assembly lube, thread the stud into the block until finger tight (assemble the bearing caps and crank girdle), then torque all the nuts down to 60 ft-lbs, NO MORE. Then loosen them all a few turns, and repeat. He said to torque then loosen a few times, as it polishes the threads and gives a better bite. But he definately made sure to stress NOT to exceed 60 ft-lbs of torque, and be sure to use the proper tightening sequence, per the FSM.
