Sam,
I suggest that you get a book written by Corky Bell "maximum boost" and read it from cover to cover - it will answer a lot of your questions.
I am in the process of build a turbo 292 motor that will be EFI port injected. If you check in this forum you can find a link to the turbo intake and exhaust flanges. Since I have a lot of work to do on the basic truck the turbo will be added later after the truck is on the road.
