Rocker shaft orientation?

The rocker-arm oiling-holes on factory stock tubes should be on spring side of the pedestals;
But more importantly, the oil has to be able to enter the tubes from the passage coming up through the rocker-pedestal at the second from the left, end.This is imperative.Your FSM should show the oil supply hole on the valley side of the pedestal. The oil supply-hole from the head must line up with the special large oil receiving-hole in the Rocker-shaft.If you install the rocker-shaft differently, oil will not enter the tubes and the rockers will gall in no time. Certainly long before 1.5 hours.....
And the factory rocker-arm oiling holes, to my knowledge are off-set only a few degrees; Ima thinking something like 5*?
On a 273 with very low spring pressure, I'd be inclined to ignore the orientation of the little rocker-arm oil holes, so long as they are not oiling the valvecovers,lol.
