There's a lot of info on here about head bolts and studs. Use the search function. Use factory head bolts or buy studs.

I run Mighty Diesel head bolts in my 6.7, and I torqued them down to 125ft lbs, my buddy also uses them in his pull truck and he pushes over 70lbs of boost, skip to 6:55 and its the black JD Drilling Truck

I have been running the mighty diesel ones for 2+ years with no problems. Torqued to 145 or 135, can't remember. Many 50+ psi blasts with 3 different turbos with no problems to date.

Did you chase the threads in the block or lube the bolts properly? Oil doesn't count either, it squeezes out as soon as the bolt gets snug. I've ran the Fastenal studs in more then a few trucks, mostly with street compounds seeing 65-70psi of boost too. I always clean the threads and use ARP lube and take them to 150ft-lbs, no problems with stretching or breaking thus far.
I never waste my money on stock bolts, these Fastenal bolts are cheaper and stronger so it's a no brainer... Usually jump right to H11s from there too cause there isn't enough difference in tensile strength from the SHCSs to ARP 2000s.

I am using the fastenal bolts.. Torqued to 135 and 75 psi of boost every time i drive it, but i cleaned and used synthetic lube on the threads...
Also, what length did you get on your bolts?
You can go 10mm longer on the fastenal bolts to get some more thread engagement.
