So I have a 01 cummins its pretty much stock other than I have a 62/68/12 with a quadzilla on level 4. I currently have the defueling setting set to 35 pounds because I am on stock bolts but I just learned that drive pressure also affects the head gasket and the ratio needs to be 1:1 correct me if I'm wrong but that's what I've read. How do I figure out what that pressure is at and how do I fix it? In the future I do plan on doing 7x0.12 SAC injectors, DAP valve springs, Hamilton Extreme Duty pushrods, and ARP head studs. Whenever I go to do all this I also want to pull the head and get it surfaced and ringed if ringing is needed.
