Default Decided on Mods

As many of you may remember I had some head problems (with the car not me...well) anyway here is the list of performance parts I have decided on:

- CompCams XR269HR cam with a 218/224 duration @50, 495/503 lift, and a 112 lobe separation.
- Heads, minor port work, new stock size valves, 7/16 studs, hardened guide plates, new springs
- CompCams 1.5 Roller rockers
- New roller lifters, new push rods
- Roller timing chain
- Accel TPI base
- Edelbrock water pump with a 180 t-stat.

After I get this move thing behind me (I am moving from Phoenix to Charlotte NC) I will be adding larger injectors, better flowing runners and porting the plenum, possibly with a larger throttle body.

I am checking on a new chip any suggestions for that? Im pretty sure that the car will not idle with that cam and the stock chip what do you think?

Thanks for all the advice recently.
