Hard Chrome Rocker Shaft ?

OK I dug up an old pair of rocker shafts, one set from a 273, one set from a 318.

When you put the shafts next to each other they are made the same 100%, holes, oil holes, notches etc.

So that being said, when the notch is down the oil holes out toward the exhaust the notch on the passenger side goes to the front o the engine, the driver side notch goes to the rear of the engine facing down too. This gives you the oil holes pointing out on both sides as they are suppose to be.

So for the 3rd time I pulled the new shafts off and put them side by side. and even up against the old shafts, the notches are on opposite ends, so to get the oil holes out to face the exhaust side you will face both shafts with notches down and to the rear of the engine.

So I guess the heck with the notches huh! Just go by the oil holes on new parts...
