With the supercharger bolted on, I doubt its going to make much difference what head you use. Especialy if it never revs above 7500rpm. Just be sensible, match port the manifolds and stuff, it will work. Power will come from different camshafts, and supercharger pulley.
Read the other 20v vrs 16v threads. People say its way easier to just use a whole 4A-GZE.
