Yes, the holes, grooves, and weep holes DO line up on early model rocker assemblies that have the open tube at the oil connector that vents excess oil. Later heads had rocker shafts that ran full oil pressure, had a pinched-off oil connector vent, and had grooves in the rockers thast did not line up with the weep holes. The oil holes in the shafts face downward toward the head in all the applications. Decades of mixing and matching parts can result in all kinds of mismatched assemblies.
