Just going off the SHM book, the Fr500 out flows the 03/4 cobra/mach/maruader heads down low.. but there isnt a big difference after that. From what I have read on the mach1reg and corral, most guys just get the 03/4 cobra/mach/maruader heads and then the fr500 valvetrain package.

yes! for the price, the FR500 arent much better then the 03/04 cobra heads. for the value, the 03/04 cobra heads are the best 4.6 4v heads to get, and their even better if ported/polished. many people, like said above, get the cobra heads, fr500 valvetrain, and port the heads.
