The ideal Turbo head? 934? 935? Stock Turbo?

Just curious as to what criteria make for the ideal head for forced induction on the 3.0 or 3.2 engine. Why did the factory have such large I/E ports for the early 934 and 935 engine (41/41), and such smaller ones for the '76 street turbo (32/36), and smaller ones still for the late 70s turbos (32/34)? Furthermore, is there any difference, in either structural casting or metallurgy, which sets the Turbo head apart from say the stock SC or Carrera head? If one is turboing one of these engines (which i am) is it worth it to change to the Turbo head on a top-end rebuild, and if so, which head should be used? Thanks to all and Merry Christmas!
