No certain level. Boost doesn't kill headgaskets. Drive pressure does.

There are some VERY hot trucks running stock bolts.

Most say when you reach 40-45 psi but displacedtexan is right is tuned right you can run way more than that

My boss is pushing over 50psi at times with stock bolts but his head is fire ringed to keep the pressure in the cylinder better and not blowing the gasket.

letting your truck warm up before beating on it is a key factor as well.... drive pressure is a huge one, but drive pressure and back pressure are a cause/effect relationship, so opening up your exhaust prior to the turbo can help (gasket matching)

most guys say 40psi ish on stock bolts....
some guys say retorque headbolts.....

the HG in my truck was toasted when i bought it.... and after doing the head/swap gasket after fighting with it for a year, i shoulda just threw a new gasket in right away... it really is NOT that hard.

some guys get 50/60/70 psi or more on stock bolts....

i'd say driving habits, timing, egt's and turbo setup will dictate how far you can go...

I ran a 471 at 55+psi no problems on stock bolts, but drives were 64:55 so pretty low. Then gave her a healthy shot of a 200hp shot of spray... and boom she blew the hg.
