I think the Eboks can even be machined (seats cut) for the 2.25s. I believe KC's stage III FE Eboks have the 2 .25" intake valves. Non-CNC'd, I think the flow capacity between the 2.09s and the 2.19s would be minimal. I believe it's the CNC process PLUS the 2.19" intakes that really increases the flow, around 320-340 CFM @ 0.650" intake valve lift.
