All,
I'm putting together a 59A I've just gone through, and I have reused the original head studs, replacing a few damaged ones with other spare used ones so that all are in excellent shape with good threads. Stock 59AB iron heads.
I cannot get most of the studs to more than 52 ft-lbs without the studs feeling like they are stretching/yielding. I tried a few in a cracked block, and 60 ft-lbs will break them clear off.
I am using new plated nuts from Mac's and 10W-30 on the threads and nut faces. Has anyone else seen this?
I have one head on and all the studs took a solid 50-52 ft-lbs. I have yet to do the other side. Should I pull it back apart and replace all the studs?

Who do you recommend getting studs from?
