does anyone have a picture of the stealth heads next to 906's, 346's, 915's, or any of the good iron heads, im curious to see how "stealth" these heads actually are, i was tossing around the idea of getting the stealth heads that have been ported by modern cylinder head from 440source then getting better locks retainers and springs for my car over the factory iron heads, but the car still needs metal work so the engine combo is undecided besides 440 sixpack but i want as close to factory look as possible, and are these heads even worth getting for that matter
