CNC head from HEADWAY PERFORMANCE
CNC head from HEADWAY PERFORMANCE
Just got my head back from headway performance looks amazing (dont mind the cell phone pictures) CNC port and polish, O-ringed, Valve job, New guides, Supertech dual springs, Supertech Ti retainers, Supertech intake and exhaust valves. Going to be running kelford 272's on this head for now.






Looks nice, but how does it flow?? Can you post up the pre and post port flow numbers for both intake and exhaust (.100-.500 lift @ 28") as well as the before and after volumes of intake ports, exhaust ports and combustion chambers?
i dont have the specific flow charts for my head, for general idea he does have something post on his website about it. Maybe when i pick up my block i will ask if he has paperwork
