273 rocker arm adjustment

I would go with the last pic 3/9 o'clock red straw locations & go with a smaller hole on the 3 o'clock side for the valve tip oiling as opposed to offsetting the 3 o'clock hole, since it has been brought up that the tip requires less oil. I would want em both drilled thru the shaft while on base circle so there would be a bit of dwell time for oil to shoot out. Since alignment is critical/precise both when drilling and when going together for final assy I would want a full circle hole drilled as opposed to a partial eclipse & use a smaller drill bit instead for the shaft drilling to modulate the flow. I would still go with the 1/8 on the rocker but less on the shaft to control it that way. alignment is a pain/needs to be dead on & a larger rocker hole helps in this regard. #1 get the alignment DEAD ON before you drill.
