Armond:
I poked around on the Wallace Racing (Caclulator) web site and it has just about everything you'd want - including just the head flow calculator I was interested in. I'm sure I'll be back to that site from time to time. Thanks again for the help.
CNC-Dude:
The Wallace Racing calculator estimates just shy of 280 cfm for the example I used in my original post. Good call on your part!
