Short of checking the obvious, collapsed lifter or flat lobe, I don't have an answer, but lean toward a bad lifter. Was it ticking before rebuild? Perhaps there's a restriction in the pushrod body or oil passage to that lifter. You have good oil pressure? Have you run it with the valve cover off, (with oil restrictor clips), to see if it's oiling?
