If you are planning to make 500-550 at the flywheel you won't want to use out of the box heads really. A few of the brands like AFR can be run out of the box because they are CNC cut, but you will still need them gasket matched to your intake anyway.
Heads really have to be shopped for to match the cam. So your first decision may have more to do with how hard you want to spin it and how much maintenance you feel like doing to the motor throughout the season.
I would suggest talking to JSPerformance, TMR, or SSP to get all your questions answered before you start spending money. If you want expert level info, it is best to go straight to the experts who do it for a living.
Good luck with it
