was wondering if anyone could tell me the visual differences between the evo8 and evo9 heads other than the valve cover the reason im asking the evo9 i bought was supposed to be stock unmolested...well it looked like it until my tranny started grinding so i sent it to shep and it turns out its a 03 evo8 trans just kinda hoping everything eles is whats supposed to be in it.thanks

 

Two cam sensors on the back of the cams
