Matt - the first thing to dispose of is that HV oil pump. If you have good clearances, the standard one works just fine and the oil stays where it's needed instead of in the heads and valley. Been a long while since I had a 460 apart so have forgotten how good/bad the drain back is, but Ford, IMHO, didn't do a good job on other engine size heads and valleys.

Now, if Pat or Jerry would chime in
