EFI or Blowthrough?

the guys with efi will obviously say that it's the way to go and vies versa for blowthrough I suppose.
mine is a prosystems bt carb. it was on my 360 with vortech v2 supercharger. when I decided to go turbo I contacted Patrick via his forum and asked what changes would the carb need. his reply was that it would need little if any change and it would adapt itself nicely. couldn't work that out as we went to 85 jet primary from a 68 and 107 rear from 86. the rear has no pv also and I think it should. i'm no expert but from what I have read on various turbo forums bt carbs have pv's front and rear.
would prefer to stay with the bt cause i'm getting the hang of it now.
