Stock rocker shaft oil hole orientation

Every ***'y diagram I've seen shows the small oil holes pointing "down" away from the bolt hole centerlines. Don't worry about the notched ends, as many were notched incorrectly. (and I'd say the shaft on the left in your photo was made incorrectly, but it may still be useable)

hmm, do you mean the shaft on the right is wrong, because look how far off they are clocked compared to the drawings. seems like the one on the left is correct.
