The larger valves may increase volumetric efficiency (VE in Panic's post 9). He estimated 95 percent VE. Really difficult to get above 90 percent in a street normally aspirated stovebolt engine.
Note at 95 % the engine could use 441 CFM at 5500 RPM.
So at 90 % - 418
And 100 % - 464
Where is your absolute redline, and where is your practical (street) redline?

I came up with roughly 400 in my calculations, when I was running my own numbers. I think I used 5000 as redline, but it will never get revved up that high.
