Hand ported Indy T/A head pics

No need to cc them...area is 2.5" at the pinch, 3" at the short turn and bowl is 2.050 with a 90.5% throat. Keeping the air attached at those high lifts was the goal because the port is still really fast!
But I was able to control the air pretty well considering the speed...286cfm at .500 and 300 cfm at .550 lift. The jump in flow every .050 is what I wanted and was able to attain with this casting...
