Verdad Gallardo If it were my car, I would re-torque with the ARP bolts. I did with the studs and found that it was needed. You must back off one bolt at a time and then re-tighten to do this correctly as the torque measurement is a running torque.
I remember reading somewhere that you ought to either disconnect the exhaust system from the heads during the re torquing procedure, but it seems to me that if you are going to loosen and retorque the head bolts one at a time that having the exhaust still attached would do no harm. What do you think?

Exhaust must be removed and slid out of the way. I planned ahead and didn't use my new exhaust gaskets until after the re-torque and also didn't tighten and button up the exhaust.
Whether the OP does it or not is up to him, GM gaskets may be less inclined to leak. I backed each nut of my studs off 1/8 turn and on average used 1/4 turn to get back to the torque reading. I am running Cometics. The engine builder I spoke with who frequents this board also recommended this and does this on every motor he builds.
