After torquing the nuts, what was your gap where the front half meets the back half? On mine, I never used a torque wrench. Theres a spec floating around that says you are supposed to tighten until there is a few thousandths gap but I always just run them down tight.
Also just a tip, when tightening and removing the nuts, take your time and do it in a criss-cross pattern as long as the nut is in contact with the outer half. I killed a ton of studs on my first set of H1s because I just ran them out 1 at a time. It seems to put excessive strain on the rest of the studs and causes them to strip or even round out the splines on the press fit. I always put them together with a ratchet and socket as the impact goes too quick on each nut.
