when I had the 16V heads done , by Harvey Resnick , a engine builder /racer with 30+ years exp . He used a flow bench to check his work as he progressed , but relied on very carful measurement's based on ratio of valve size and the shape of the intake port. A lot of time was spent on carefully shaping the bowel and to creating a slight swirl effect in the intake . The " MAGIC " was in his years of experience and knowledge . The intakes flowed 280 -282 cfm when he was finished , I forget what the ex flowed
Basically this is unheard of in wedge head and you are talking the very best pro-stock heads NASCAR heads to get anywhere close to that. Those heads have very tall ports and the valves are not inline but "twisted wedge" and the valves are also canted which directs them away from the cylinder wall. Unlike the 2 valves heads in our engines that get closer to the wall.

O.k found the standard flow figures for you,
0.050".....25.5 cfm
0.100".....54 cfm
0.200".....111 cfm
0.300".....159.5 cfm
0.400".....192.5 cfm
0.500".....212 cfm
0.600".....216.5 cfm
I rounded the numbers to 0.5
Hope this helps
