First off I'd like to thank all you guys on here that know your stuff and share your experiences with everyone. As you can see I don't post on here much but I do read on here alott. Anywho, I'm doing my first ls turbo build, just a simple t4/7675 turbo, 5.3 l33 block along with dart pro 1 heads. Im using arp head studs and My question is are you guys torquing these to more than spec due to running boost? Also, are you retorquing them after so many heat cycles or miles? I did a search but only found threads on n/a stud torque. Any input is greatly appreciated!

I torqued mine in 3 stages 30lbft 50lbft 70lbft. Then torque the 5 small studs to 22lbft. I did not re torque after heat cycle and have had no problems.

Im at 80 lbs (with oil)on stock 3 layer gaskets. No issues-studs where still at torque when checked 1 month later. This was with AL and Iron blocks

The manufacturer specs are in place for a specific amount of stretch on the stud, no reason to exceed that.

Thank you guys for your replys so far. Sounds like ill stick to spec as suggested. So are arp head studs reusable then, like if I have to pull the heads for whatever reason? I ask bc I'm an automotive tech and I never reuse any torque to yield head bolts. Wasn't sure if these were considered the same?

I found answer to my second question. If anyone else was wondering They are reusable multiple times as long as their torqued properly. Thanks guys for the help!

Need to use the proper lube as well

And a proper torque wrench

Aaaand depending on what lube you use you will be using different torque values...

There are much better charts out there for that but Google wasnt playing nice with my tiny brain and lack of patience today...

And also important is to lube both sides of the washer, and under the nut or bolt head
