I had those heads on my '69 Camaro back in the day, when they were "the head" to have. I was also running them on a 331 (not a stroker, just a 327 punched out .030). I also changed out the press in studs for screw in studs. You rip one rocker off at higher RPM and you don't use press in studs ever again
I don't know about 500hp, but I do know I was running 12.9 in the quarter at around 103MPH (with horrible 60' times and bad street tires), so I know there was some good power there.
As others have already said, those heads are pretty much worthless these days, unless you're looking for a numbers matching resto.
