Don't know if you found an answer to your problem, but I torqued the ARP studs to the original torque specs of the 2.4 SRT or PT GT engine. I can't remember off the top of my head, but the ARP studs are sturdier than the original bolts. You don't need to torque them any more than stock.

If you're using higher boost levels than yes torque them to ARP specs. I was only running 18 psi and it held up for about 15k miles... then my car was rear ended... so further than I can't confirm.
