headstud max boost

[idibeast]

Hi guys, so the truck is back together, and I'm back to building it. I know that the stock headbolts are only good for about 12 psi, but since I installed a set of arp headstuds I was wondering how much boost these studs will hold. The truck is a 1985 6.9 and I was wanting to get it up to 20 psi, is this possible without decompressing the engine? Thanks guys.

Seems those running this kind of boost are doing fine with studs. I think the biggest thing is getting your turbo to turn those kind of numbers, fuel, air flow, etc. all influence the amount of boost, not to mention the type of turbo, waste gate settings, etc.
