20V vs 4AGE 16V with big valves

Hello,
4AGE 16V head inlet 2 x 29.5mm, 2 x 25.5mm
4AGE 20V head 3 x 26.6mm, 2 x 26.0mm
4AGE 16V (custom) 2 x 32.0mm, 2 x 28.0mm
My application is a SC14'd supercharged 4AGZE running 18+ psi.
I am wondering what would work better, a 16v 4age with big valves or a 20V head. Obviously the 20V head is a lot cheaper and also it gets you slightly bigger exhaust, shim under lifters, and a big intake hole! I am thinking I could run conservative cams with bigger valves for better streetability.
Does anyone have any comparisons between big valve and standard 4AGEs and 20V 4AGE cylinder heads?
Cheers, Nick
