Wallace Racing - Convert Cylinder Head Air Flow Depressions Calculator
The Mullen TA heads I posted to the head flow chart threads to show a flow of of 93 @ .700 @ 3.0 inches H20. The Wallace converter shows that to be close to 266 CFM at 28.0 inches H2O. I imagine with the casting revisions and the moved PR location that these heads should be over the 300 cfm mark. But one think we haven't heard yet is what condition the old seats are if they have sunk and need some additional work.
