We flowed a couple sets at Thunder Racing and found 240 cfm peak with one set and 233 with another, versus AFR's advertised numbers of 262 cfm.
The 210's, however, all flowed 280 cfm out the box versus 285 advertised.

I wouldn't get anything less than the 210's. I'm on my second set now and I like them alot.
The smaller heads don't have as much intake CNC porting as the 210's, 220's, and 227's. No matter if they are 180 or 195, they won't come near 280 true cfm.

I thought the larger CFMs reduced port velocity which reduced torque and increases HP. Am I right? So, doesn't it depend on the overall package to determine which head CFM to go with? (Engine displacement, exhaust, intake, cam, etc).

For that cam, definately. But I was inquisitive about the limits within the stock bottom end and a mild cam (224/230). Wouldn't the port velocity be reduced with such a mild cam? Wouldn't that disrupt torque? I'm not speaking as an authority, just a question.
