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.
