I recall that thread info... and wonder about 1 thing. These shafts don't see much pressure, and are not filled to the brim with oil at the lower RPM's. YR was wanting to fix the high RPM starvation of the cups where he ran his stuff, and lining up the shaft holes where they could intersect the rocker cup oiling holes at some point in their motion. But, for extended low RPM operation, I am not sure it makes any difference.
