anything that can be done to improve heads for 03 while they are off such as valves, port work, rockers and so on. Figured I would have them freshened up and thought maybe something could be done to improve performance or reliability as well

Hardened seats. So far no one has posted flow numbers to indicate that porting will really make much of a benefit. Also remember that right before the head is a intake manifold that is very restrictive. Porting the heads isn't going to get you very far with out somthing like the gogo intake.
Exactly what I was talking about. It also comes with a built in egr delete and coolant reroute eliminating coolant from the intake all together. As for in creases? It has been said that 200* degrees were lost as well as better throttle response and very noticable difference in the higher rpm range. This all on a stock truck with tuning only. Factor the power max and it should get even better. The cost of the intake is about the same as a inter cooler and delivers the same gains in egt drop plus more airflow.
