I’ve got the rocker shafts with the notch on the drivers side……facing the back of the engine.
Got the notch on the passenger side. Facing the front of the engine. Was told it didn’t matter as long as they were opposite. The oil holes look like they line up when i rotated the shaft to check alignment.
the next thing I’ll do is switch them out and trade places so the drivers side is notch facing front
the rocker arms are in the right place. stamped left and right and sitting on the valves...
No oil pressure to the rocker shafts.
