Well, going around to my final torque sequence on my turbo head I was torquing my head studs to 80 ft. lbs. per the ARP instructions and there it went, the 1/2" 12 point socket stripped the nut. Nut is now rounded off and won't come off the stud. So I am somewhere between 60 and 80 ft lbs. on one of the head studs going through the cam tower. Clearly they should have used 6 sided nuts. Yes I used ARP supplied lubricant. Yes the socket was completely seated on the nut. Took it in 3 steps starting at 40 than 60 than 80. Got about 6 at 80. I also like their disregard for stopping at 65 per the FSM for turbo apps. Thank you ARP. Probably no chance in hell I can back the stud out with an allen at this point.
