Default ARP/Head bolt TQ question

I just put on a new set of heads and used ARP head studs. This is on a boosted motor that will run about 10psi. I Torqued the big ones to 70 and followed the pattern... Now I'm wondering if I should go back and re-torque after a few heat cycles.

What do you guys think?

I really don't want to tear it down again, but it would be better than the heads lifting.

Some will tell you to retorque, but I never have, and have never had a problem. The torque is 70 like you said, 140 would cause some damage on an aluminum block.
