I think you`ve got it covered but for the oil plug by the dizzy being drilled with a .030" hole to lube the gear and then seeing as you`ve got a pressure plate pushing on the thrust bearing I would do this mod,
Take a small fine file and make a channel that runs from the oil hole in the thrust bearing down to the thrust surface face.
This channel only needs to be 1/16" wide and .020" deep to keep that well lubed!
Next might be to get the 90 degree meeting point of the oil return passage from the side of the block and that oil galley rounded off some.
To so this you need a 6" long grinding burr with a ball end small enough to get into the passage and attack that front facing edge.
The only other thing would be a oil temp gauge so you can see if you are in need of a cooler to maintain temps at no more 250.
