273 rocker arm adjustment
i see what you mean about how if those two holes are lined up at the same time...the oil pressure inside the rocker shaft will drop. i kind of like your idea of drilling the hole under the rocker arm at a different angle, so it doesn't line up with the other side. I drew a red drill bit onto the previous drawing, is this what your thinking? i looks as if the two holes will still end up being pretty close to the same spot.
