I have a 2002 6.6 that got too hot when water pump failed. It has soot or carbon in coolant tank but still has good pressure. Maybe too much pressure! Any ideas?

Sounds like a head gasket.

Thanks, I was afraid of that. What about a cracked head? I'm hoping not, but want to be prepared.

Maybe but, lets hope for the best. There is a way to tell which side has the issue but, I do not remember.
Maybe someone else will chime in.

What T F, over
It involves disabling the water pump drive (hard to do on a gear driven dmax pump), draining down the coolant level slightly below the t-stat opening, stat removed, to see which side the bubbles come from. Something like that...
