ARP Stud upgrade need to know wtf folks are doing for torque

I know ARP says what they say...

Ive been doing the reading here, there, and everywhere...and it seems some folks are saying that 80ft lbs for the larger stud nuts and 25ft lbs for the smaller top deck stud nuts is too much? And, that a lot of people are going more like 75 and 22 for that combo...

From what Ive read, the trouble comes when you do passes with like 5-10 minny torques up to the final number...Ive been reading where the 3 pass up to desired tq is the ticket...

Thanks for the help guys...

This is a factory LS4 325ci (5.3L) just a shorter crank to put it in sideways

car is boosted 10-14psi switched to the studs and ls9/a gaskets

I don't understand the arp #'s. they are for the integrity of the bolt with no consideration to pulling the AL threads out of the block.
Or does someone have usage specific #'s?
