Indy Cylinder Heads has the complete package already worked out for the race drive setup. Everything from the motor plate to the carb all you need is the charge tube. We put one on a 540 -1 motor in a dragster and the only change we had to make was taking a little jet out of the carb. Best so far is 4.13 at 176. F3R 112 with the 136 gear set.
