They are the real deal. They port heads for real racers at the very top of racing. You can run them down all you want but they port heads you will never see in in your life on engines you could never hope to play with. While he was playing with TOP FUEL cylinder heads you were in your garage play with what you could find.
The more you run them down the more people will see you for what you really are. If ultimate factory iron was your game you would be doing Stock eliminator and Super Stock heads......Maybe you could show us all these record setting engines with your heads on them?
