I run a set refreshed by Dwayne Porter as well. Great to deal with, very well informed and extremely experienced.
I would likely go with the CNC'd Trick Flow heads and have Dwayne go over them if I was building a new motor though.
Why are you stuck on the Indy EZ's?
If the Trick Flow heads were available when I built my engine I would have bought them. Much better finish everywhere and the ones I have seen look like you could bolt them on out of the box with only a basic inspection. Not like Indys where you basically have to re-do the valve job and size the guides before you use them.
