oil pressure and adjustable hydraulic valve adjustment

When I first broke in the engine, my mechanic set the adj valves. It ran great and did not overheat. We discovered that the oil plug under the distributor was left out and caused low oil pressure. I have since installed the missing plug. My question is....Do the valves need to be reset, due to their being set with low oil pressure? I forgot to mention it now runs terrible and gets really warm +190.6.
Any insight would be greatly appreciated.
As part of my study of the issue. I found that the adjusters are 24 threads to the inch. That doesn't square with Compcams suggestion of 1/2 - 3/4 turn after zero lash. To achieve 0.030 to o
0.040 cushion.
