I forget the original reason I rang him for but we got talking about 16v 4AGE and how I wanted to attack one with a milling machine to rehsape the inlet port so it'd angle down into the head like a 20v one does.
That guy had apparently already done it, and said that at around 10,000rpm (I think, not sure but it was very high revs) was getting a bit over 290hp from it.

I know a guy who is currently looking into this very thing (he has borrowed all my spare heads for development). According to his calculations based on the biggest inlet valves you can fit in the head (without moving the valves), the most a 16v head can flow with ideal porting is 260hp.
