Not Ranked
A bit hard to tell until you get the valve guides replaced, and the valves reseated.
The roller should start on the side CLOSEST to the rocker shaft, sweep over centre, then be on the side OPPOSITE of the rocker shaft AT HALF VALVE LIFT, then sweep over centre near full lift. The pattern should be near centred over the valve stem, the narrower the better.
Your rocker does not have that pattern at all.
Put some engineers blue on the valve stem and watch the pattern the roller leaves.
