More tid bits to consider...
It is my understanding the as cast (no port work) High Port heads have about a 277cc intake runner volume. Also the High Port head uses a large 2.200" intake valve at a taller 2.000" installed height, thus a longer valve stem length at around 6.200". That is something to consider when evaluating the spring pressure to control the valvetrain mass involved.
Regarding the Torker II intake. Ken Crocie used one on a 535 cid combo that made 650 Hp. Nothing elaborate other than necessary TIG-welding above the ports, which needed to be machined flat and then port-matched to the tall cylinder head ports in use..
