As you can see by the many responses, this simple question is like a secret. I've asked before and didn't get much feedback. I torqued my heads to 80 lbs with ARP bolts and some folks torque higher. Most of us don't run 14 lbs of boost anymore. I don't like the 60 and I don't think many others do either even though "it's a secret". I've had no problems with the higher number.
Well I'm no expert but I torqued mine down in 10# increments, loosening a 1/4 turn 3 more times in the next two days and retightening them (the car was not started no tranny at the time) to 85#s. I was using stock irons felpro 9441s, and ARP bolts. So far mine has held with out a problem. Good luck man
