Head Studs and Studded Tunes

Hey, 1st time user here and new member so please bear with me...

I have a 2006 Lariat 6.0L that my dad bought used for a work truck at 140k miles, that I'm driving now that he has a new truck. I've been wanting to put ARP head studs in for a while now, so just last week I received a present; I discovered that the truck already has head studs instead of factory TTY bolts. The truck now has 290k miles free of headgasket issues. I've run pre-loaded SCT performance tunes (hard on the pedal) for over half a year, non-studded hot custom tunes as a DD, never had a problem.

I guess my question is: is it safe to purchase and run studded tunes? I know that if the head stud job was not done right with the previous owner, then I may end up having to pull the heads and pay a lot of $$$ and possibly have to replace cracked cylinder heads; an expensive endeavor for an 18 yr old. The truck is deleted, with stock injectors and turbo, so I shouldn't have a problem if there hasn't already been a blown gasket issue in almost 150,000 miles, right?

I just want other's opinions before I buy a studded tune file, I will probably be running a tow or mild street tune, no go fast/race type files. Thanks

The money you save with a lighter foot on tires and tickets will pay for repairs. Just kidding.
Iíve read here that with non o-ringed heads, even with studs, itís a matter of time before gaskets blow again. Iím sure there are other factors involved like gasket type, which arp was installed, driving habits, and sheer luck. Iím sure others more knowledgeable can give better guidance.
I personally donít like running hotter tunes because I donít like seeing 9 psi of boost cruising down the highway. Iíve reliably run 30+ psi on arp studs, but it was on a built 4g63 -- a totally different engine than the psd.
I can understand the grin factor of a big diesel surprising the guy at the stoplight. I get it, but do you really want to go that fast in a big truck? Things happen fast, and itís not impossible to break traction and bring the rear end around, even in a LWB truck. My .02. Be safe
