its right arround 620+fwhp with carefull tuning.... i think you should look into some better flowing heads to take advantage of that cam and big bore... AFR 325, Pro-filer 320, or Pro Toplines are all worth atleast 30-50 horses over the gmpp heads.. or have the heads ported.. you want intake flow numbers in the 380-400 range for that engine and cam (IMHO)

Ya, I have already decided that a head swap would be in my near future.

how high do you plane on reving the motor? ~310 would work if you keep it under 6500-7000rpm wont have a lot os hp but you will have a button of tq

2.3" intake will be bennificial to the 4.40" bore of the 502
