Oh yeah! I would suggest anything to keep that drive pressure down (EGT primarily) to help keep them from cracking heads! I believe cracked heads (and valves) were more common in our shop than head gaskets. Cracked pistons are the next most common behind head-gaskets probably. I'm not sure what powerstroke is worse for piston failure but they were up there. Funny thing is, we used to dyno a few high horsepower (800+) 6.4s and they would lift heads (push cylinder pressure into the cooling system) when loaded with stock bolts or studded, and the gaskets would seal right back up at lower horsepower and be just fine.
I don't think it was uncommon to see over 80 psi of drive pressure, but it's been a while since I was looking at logs.
I usually say, I wouldn't expect to pickup much HP if any, but usually efficiency!
