What are you guys seeing with your own heads, and how much work to get those numbers?


Stock @.600
Eagles and 6.1 heads 300cfm
Apaches around 335cfm

The 3-4-5 numbers are really awesome on the g3s. Eagles hit 300 at .5


What about the exhaust flow on the Eagles? I understand the exhaust is only 55% of the intake? I'll have my newly acquired Eagles on the flow bench next week, but always interested in what others have seen.
