Unfortunately, you can perform an entire list of upgrayedd's that will pick up as much or more power than the heads alone without going into the engine itself, but if you have ambitions to build a motor without a power adder, then the Ford Racing M-6049-M50BR and M-6050-M50BR heads might be on that list.

Excellent that's good to know for future reference.
