It appears that the drilled oil gallery to the head is off slightly with the block. It's probably in tolerance with the factory spec, but I agree, it looks wrong. So to correct this issue, you would need to pre-file the oil hole in the cam bearing to match the block. Remember to slightly chamfer the modified oil hole (both sides) on the cam bearing prior to install. Also DO NOT reuse cam bearings, once they have been pressed in, they are not re-usable. Good luck with your build!
