Mini Me swap help!!

Ok I have a few questions regarding this swap. What head is better the d16y8 or the d16z6? Also I have 2 engine blocks in my garage that I can use...they are the d15b2 and the d15b7...which one is the better choice. Also can I use the PM6 ecu for the mini me swap or will I have to get a different ECU?

Well, to me, the difference in performance between the two heads is negligable. I would just go with the one that has less mileage on it. Same goes for the blocks actually. Granted, I dont know everything about the heads and blocks but thats just my input.
