Going to head studs, what Torque to use?
I did some searching and didn't find a answer. When I do this head /cam swap, I have a set of head studs to install, just wondering what do the nuts torque to and is there a procedure to use. I know the torque arrangement, just wondering if several passes increasing torque to the final value is suggested. If anyone has a suggested procedure I'd appreciate the info. Thanks

If the studs you have are NOT ARP, I would not recommend using ARP instructions as you may damage the block or have incorrect TQ

My new studs are not ARP. I have to ask this, how could using ARP's torque values on my studs damage the block? I assume your considering my studs will/might not stand the ARP's torque?

I used ARP when I swapped in heads/cam years ago. Torque value on ARP's using their proprietary assembly lube on an LS1/6 is 80 lbs. ft. for the stud nuts and 25 lbs. ft. for the bolts. You need to use the factory tightening pattern with three progressive passes to hit the spec. I used 25, 50 and 80 lbs. ft.
You should contact the manufacturer of your head studs and check what they recommend for the brand you bought.
