The head stud is in the way of the valve, but looks like the rocker needs to be raised.

Longer pushrods are needed but may cause the rocker to push on the side of the valve stem tip instead of the center, that would require filling the bolt hole and re-drilling it further towards the cam. Or you could offset drill and tap the hole to a bigger size stud
Of course all that makes the PR angle worse than it already is
Just measure the width of the sweep pattern, that'll tell you if the geometry is correct. If it's less than .600 lift it should be less than .025 on the sweep. The closer to the center of the valve the sweep is, the better off you are, but it doesn't have to be perfectly in the center to have good geometry.
