The FSM has this information in it. Perhaps someone has it digitally stored and can post it.

On R & RB motors, the holes are positioned at the bottom to feed oil to the highest load area on the rocker arm, and if your holes are offset from the hold down bolt holes on the shaft, make sure to orient the small oil feed holes toward the side that best locates these holes closest to the center of the highest load bearing surface (fulcrum) position inside the rocker arm's. On B & RB motors the holes are offset to feed oil to the center of the loaded area of the rocker arm itself, and that translates into pointing the oil holes towards the exhaust side and note the intake side.

In other words, the oil hole goes at the bottom and in the middle of the rocker arm's sweep pattern on the shaft.
