I think circle port heads have only one stud between each pair of intake runners. The oval ports have two studs, one on each side, on each pair of intake runners.

I dont know if the original post i wrote went thru. regarding gx parts, im still getting used to this program.
(Jesse i got ya message ill call soon!)
ANYHOW, does anyone know if there are serial numbers or anything on GX heads that you can use to identify them, WITHOUT taking off the intake/exhaust manifolds. And for that matter can anyone tell me if theres a way of identifying circle or oval port heads too
