Air flow numbers for a cobra head?

[JimV]

Does anyone have airflow numbers for a stock 4.6 4V head from .01 to .05 lift?

 

[bullitt1723]

Stock 4V heads flow 260 cfm intake and 201 cfm exhaust @ .550"

Fox Lake fully ported 4V Modular heads flow a whopping 320 cfm intake
and 260 cfm exhaust at .550" !!!!
