I'm going to guess that the only reason they found residue on the piston was because #6 wasn't firing correctly.
I'd just run it with new injectors and keep track of oil consumption. If it starts getting high, then consider a rebuild. You don't have to replace injectors again at rebuild time either if they're working properly.
