Reworking the 273 Adjustable Rockers

I guess I'm not sure I understand the need for this mod. At no time do the rockers get "full oil pressure" unless you change the method of oiling the top end. In factory oiling the holes line up to expose the shaft to operating pressure for a few degrees out of 360°. I'm guessing something like 15-20°? So what's felt is a pulse which is then dispersed over the whole shaft because the oil pressure is leaking out the shaft and the sides of each rocker.
I wouldn't use these rockers for "big springs" or "big rpm". And if I was building for those, I'd probably be swapping to pushrod oiling.
