Just have a few questions. 1st= how much boost can stock hardware handle? 2nd= should stock hardware be retorqued? 3rd=I have no idea what is in my truck. Is the stock hardware, bolts vs. Studs, and if I pulled the covers would I be abke to check torque? I am wondering if there is anything I can do as far as preventative maintenance to keep head gaskets from failing. My turbo maxes out at 11psi. I have no idea how old the turbo is, when it was installed, or if it has ever been gone through. The GV was done when the truck was new, I have the original owners manual that's dated for instal. But I have no idea about the turbo kit. I had problems with a 6.2 and head gaskets that was turboed. Finaly did ARP studs.
