Just realized a lot of guys are torquing head bolts wrong on 6.7 Cummins

I was helping a buddy swap heads on his 2013 Ram 3500 last Saturday and noticed he was doing the final torque in one pass instead of in stages. The spec from Cummins says three steps: 90, 145, then 175 ft-lbs on those 14mm bolts. Skipping the middle step can warp the deck or cause gasket failure down the road. Anyone else run into this with the ISB platform?

Learned better" sounds like someone made you feel wrong for doing it your way.
