Reworking the 273 Adjustable Rockers

Agree to disagree. There is so much oil splashing around under the valve cover that everything gets oil. Now if you gave a 8,000+ rpm race engine you might want to make some modifications. Mopar never has had a problem with rocker arm/shaft/pushrod failures with stock engines (100,000+ miles) so oil hole orientation is not an issue unless you want it to be.
