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.

will the intake make noticable difference on something with only tunes, powermax and stuff or would it only be noticed on something that was race truck? I could have the intake done but cost a buck no matter where I take it as I cant weld aluminum and would want it done right

You can do a three angel valve job bigger valves stronger spring but you would need this intake

GoGoDiesel Stage 1 Intake Manifold w/ EGR Delete The only true performance intake manifold on the market for the 6.0L powerstroke. [GGD-6LSTG1] - $1,200.00 : Direct Injection Performance - GoGoDiesel.Com, Your Source For All Things Diesel!

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.
