I currently do not have my heads to measure some stuff out and won't get them back until Wednesday and I need some measurements for a CAD project I am working on. Can someone please give me the intake port measurements off a set of heads and the distances where the manifold bolts go into the heads and the distance between the ports? I believe the bolts that the manifold uses are 6mm too, but correct me if I am wrong.

Thanks,
Justin
