Priming 340 engine and rocker arm oiling.

I was surprised that the pass side had 12 degrees of oiling and the driver side had 34 degrees of oiling. I'm not sure what caused this and I don't think it will be a problem. Also it's not my motor. When the opportunity presents itself on one of my own motors I will mock the cambearings to the camshaft to see how well the holes match.
It wouldn't surprise me if different cores are timed differently. Also I think how the cam is timed to the crankshaft will have an effect on the oil timing even if the holes are the same on the cam.
