Arp head stud question?

[92_talonGsXt]

I just got my rebuilt head installed with arp head studs and drove about 200+ miles,how many miles do I need to drive until I have to torque down the head again, and how much torque should I torque down the head to?

I re-torqued mine after 4-5 heat cycles, which was about 150 miles. They have held for 6000 miles. I boost about 25-30 psi depending on the gear.

With moly lube they get torqued to 80. I believe I re-torqued mine to 90 to make sure I would move them some. Plus I believe some oil gets down the threads, so it isn't all moly lube anymore.
