ARP head stud torque

Just wanted to get some opinions from some of you knowledgable folk. I've asked on here before the torque steps to tightening head studs. Ive settled on 50,100,135. I have a box of ARP's here for a customer's truck, and they say only about 92ft-lbs...?

Re: ARP head stud torque

If you do it without pulling the heads off you need to replace them one at a time and torque to stock head bolt spec. Then when the entire head has studs continue with the ARP torque procedure.

I torqued mine to 135 using the stock (120k mile) gaskets and have not had a single issue.
