Head Porting? good or dont bother

Does it help to port the head on a forced air motor? What kind of numbers can u see? Does anyone know who does a good job porting a 24valve commen rail head and what it would cost?

PDR does head porting for 12V and 24v

PDR does porting, looks like CFM can go to over 181 CFM from 161 CFM. Don't know how great that is (although it's pressurized so it's more than the equivelent improvement on a gasser) but it's here:

Porting is always good if you like lower egts, better efficiency, and more power
