Pretty good. Some slight corrections: the banana grooves would go in the shafts at 6 o'clock across the already there 15 deg offset holes (If I was reading that situation correctly). the hole in the rocker on the valve tip side that goes out toward the rocker arm/valve tip interface needs to further up like in my pic/& was commented on later as opposed to being in a straight line from the other side. I turned the cam bearings to block flow up to the heads (cam bearings are a notorious leak) & I drilled thru each angled gallery on each side of the valley & on down into the main galleries so they are being fed full time then up at each deck I drilled/tapped into each oil gallery (the top of the 2 angled passages) for a setscrew drilled to 0.0625" . Point taken on 0.100" being too much for the valve tip side (I'll reduce it on my next one). The shaft bottom (6 o'clock) holes are much larger on a non banana grooved shaft than they are on an OE banana grooved shaft & may or may not need reducing & on an earlier Q, with the shaft haveing 3 holes now, I think the load bearing arc fulcrum should be getting plenty of lube. #1#1#1 get everything mocked up DEAD ON before scribeing the dykem (you dont want to have to do it again!) EDIT & I drilled new holes in the cam bearings vertical from the mains, 1/16" which is plenty for them
