SB Head Oiling modification

If you're looking for full time rocker oiling I'd be curious why you think you need it. It's typical to do for continuous high rpm use and needs a larger capacity oil pan than stock.. Think road race/circle track type stuff. It also should involve lower end mods because you are effectively creating a much larger internal system "leak" that will take oil away from the mains and rods. You can do similar stuff by just using hollow pushrods.
