I was wondering about changing out the bolts to studs. Its a common practice on the Cummins 5.9 engines, but the head is cast iron, not alum. How would you go about torquing it? I know there is a specific torque procedure, would you remove one at a time, and torque the new stud/nut to the first stage, and then do all the studs to the next amount after they are all installed? Or go all the way to the torque value plus the extra 1/2 turn (or is it 90 degrees, I forget) on each stud before removing the next bolt?
