People don't quite comprehend there is a difference between being fastest at bench racing and being fastest on track.
Why on earth would you choose a company to work with then ask them to work with a product they would rather not??? Going to pay a professional for advise just to ignore it?

.If he was working with just a shortblock I would say the AI TFS kit would be the way to go for his money, but it wouldn't make any sense now that he has a set to work on.

well the thing is, the car is my daily driver. its my only car. what i was originally planning to do was save up for the tfs and turn around and sell the afrs for minimum down time. but im starting to consider porting the afrs. i just havent figured out how to deal with the down time

I was pointing out that it would not be a good way to spend money to sell the AFRs, to then spend MORE on new castings and then have THOSE ported.
Not wanting down time is understandable, though

Isn't comparing AI to AFR like comparing apples and oranges? One makes a casting and the other just ports them.
The real comparison is if the op sends his AFRs to Tony and somebody else sends the same casting the op has to AI. Or for lesser value send the AFRs to Tony and compare what AI can do with the TFS's or Darts.

In that case, I'm sure they are "equal" enough. Except I have a hunch that even though peak HP numbers should be similar, the AFR's would produce a superior torque curve. This is assuming of course that the user spec'd his build correctly.
