So, it is a good idea to re-torque the head bolts to make sure they are what they should be?
its would be a real good idea to check them and then crank'em down. A few sled pullers around here run head bolts and crank them down and do fine. but I wouldnt trust it forever.

How are you turning up and down the boost like that? Im new to cummins. Mine is only going up to 25 psi.
You use an adjustable boost elbow. It regulates the pressure the wastegate sees, and keeps it closed longer. You need more fuel to make more boost, though

That is what I thought, but when I was asking some questions about adjusting my valves a bunch of folks told me it did not matter unless I had studs. Guess I'll pull the valve cover again.
I'm surprised about all the variances here. I have heard 48 to be the magic number with 50 being stable. I am not going to go to rings, but will be doing studs with my turbo upgrade in the coming 2-months. I want to run a solid, consistent and reliable 48.

High boost isn't the only factor in blowing the head gasket, timing can cause much more problem.
Advanced timing causes higher cylinder pressures, excess boost just adds to it.
Don't know how the electronic timing works an a 24 valve or if the controller boxes you guys use alter timing but on a fixed timing engine like a 12 valve once you get over 19° it's time to think about studs and rings.
