I am looking at changing some stuff on my car as far as the intake and possibly exhaust and I am trying to find the difference in the c heads and ford gt heads as far as intake ports and exhaust ports and how the bolt holes line up etc. No one I know has either of these heads just laying around. lol. I have tried to find pics but I can't find anything that helps. I am mainly wanting to see the difference in sizes/shapes of the ports and locations of bolt holes.
