few things: studs will still stretch. a bolt/stud HAS to stretch to maintain clamp load, that is the nature of fasteners. however studs are superior as you are relying only on the top threads to stretch and are not fighting the friction of the block tap like a BOLT does, stretching and twisting the bolt along its entire length.
I too prefer to let the engine heat cycle at least once then retoque the studs or bolts whatever it may be. Or let it settle for a few days like someone mentioned.
alos as previously mentioned, get your arp lube on there, and i like to put a breaker bar on the nut, tighten till its snug, back off, tighten till snug, back off, tighten till snug, back off. each time you retighten you will notice the bar goes further. this will give you a true torque reading when you go to torque the nut on your 4th and final pull. THis applies to rocker studs, main studs, rod studs, head studs, bolts etc. I did my studs one by one, (old bolt out, stud in). I also went to 137 ftlbs, but these are 0.5" 7.3 studs. Them heads aint coming off!!
