		definitely replace the sodium valves.
  definitely a high RPM engine, benefits won't appear until 6,000+ RPM's.
  with a 428 crank, top revs go down, streetability goes up.  Overall, probably a good switch.  Don't know the specifics of your planned application.
  an aftermarket rocker assembly is a good idea, especially one with end stand supports.  Dove is pricey, but have a good rep (for their rockers).
