Sixpack.....bes did something similar to what you are talking about doing with their engine masters 417ci motor. 2.19 intake valves with new seats.....they actually sunk the intake valves a good bit to help with p to v. Wouldn't milling the head and sinking the valves on the apaches be a bit easier?
