I am torquing my head studs and went through 60-90-125. The instructions say to loosed and tighten 3 cycles. Does this mean to loosen all the nuts and re-torque or one at a time?
I did them one at a time. I brought them up like you mentioned, 60/90/125, and then one at a time I loosened them completely and then retorqued them to 125. And I did that 3 times. I did it in the same torquing order as originally too.
My reasoning was that if you drop them all off and bring them all back up a few times you would probably be squeezing the headgaskets all sorts of ways. I wanted to tighten them up and leave it that way. So I did them one at a time.

make sure you coat threads with moly lube or motor oil prior to torquing.
So whats the final word? If I was doing this, I would NOT loosen all the studs once they had been torqued, but do each one, one at a time. I can't see compressing and relieveing the head gasket three times as a good thing...
The little 8mm are not to be reused they should be replaced just like the fly wheel bolts.if they have been installed on a motor and were cycled before you don't have to cycle them
All the bolts or studs are the same length mine came with the small bolts near the pushrods as well but if yours didn't come with them you can reuse the old ones
