asking for opinions

I would do 3.55s instead of 4.10s. You will be annoyed with 4.10s after a month or so of driving. I would recommend 4.10s for a track only car.
Ported stock heads? Unless you can find someone to do it cheap it is always better to buy new.

Don't bother with the cam untill you get an intake and heads that will use it. Otherwise you will probalby hurt your performance more than help it. The intake is the biggest bottleneck in the whole engine. At least do it all at once if you do go that route. 3.55 or at most 3.73s for the street. Especailly if you are on a budget... Gas has been getting pretty expensive lately. Shift kit is a bit harsh on the poor AOD. A trans oil cooler would probably be better for it. If not something for the tranny get some subframe connectors sooner than later.

Actually, it will help the trans live longer. All a shift kit does is increase line pressure, which will help prevent band and clutch wear in the trans. So for the shift kit! I would also recommend the 4.10s. They will be fine for you, and will be a better choice performance wise for an AOD Mustang

I agree, I think you will be happier with a higher stall converter and shift kit plus your 4.10's than with the engine mods for now. With this add a tranny cooler as mentioned. As far as a shift kit, I would go with Transgo or Baumann. For the converter, I would look into Edge.
