Got some flow numbers today!
 
I'm in the process of building a bbc and just had the heads flow checked. The heads are Patriot Performance freedom series 320cc.

lift----cfm(flow)
.100-89.5
.200-148.8
.300-209.6
.400-259.8
.450-282.8
.500-300.8
.550-306.4
.600-318.7
.650-331.2
.700-347.8

This is out of the box untouched at 28in of water. They dont quite flow what they advertise but it was quite a bit better than the other brand they compared to. I dont wanna get into a pissin match I just wanted to share what info I learned today. 8)

There going on my low budget 468 they should work well for it. 10.2 to 1 compression. Pump gas looking for a nice 11 second street car.
