arp uses their own torque specs. check what the specs were from the original packaging. also, you should retorque the head studs after it has heat cycled once.

 

Gambo117 is correct. You have to re-torque after firing up the car and letting it idle for a few minutes then shut her down and re-torque bolts. It is a pain in the *** but you gotta do it! Also, ensure that you torque the head bolts in the correct pattern and doing so slowly and ensure you use the molylube that comes with them.
