David Barton told me the Drag Pack heads are cnc'ed but it hardly scrapes the walls. I really dont ask flow numbers because it seems the only guys on the same page are the 4 or so of us on this board all have basically the exact same numbers 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
Gen 3 power 6.22@110, 9.85@135
