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 of 52 ft-lbs without the studs stretching/yielding. I tried a few in a cracked block, and 60 ft-lbs will break them. 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? Thanks, Nick.

We always replace all studs or head bolts when rebuilding. The constant heating and cooling anneals old studs and makes them weak. Our choice is ARP studs. A bit more expensive, but cannot be beat. Oiling studs and/or nuts skews the torque readings.

Also, do not use a lubricant on studs nuts or bolts when torquing as this caused an over torque condition.
