Dont forget to remove your spray tubes and clean them
I ultrasonic clean vapour blasted parts maybe 10 times to get all the media residue out.. it's amazing how much you find.

Normally most people use ultra fine glass beads for vapor blasting, although more aggressive media can be used to remove heavy oxidation or even powder coating with rough aluminum oxide. On engine parts glass beads only.
For cleaning, definitely remove any plugs. The ultrasonic is a good first step to loosen up everything and get the media off the surfaces. For getting into holes/bores/internal passages, I would also get an air gun with a small needle tip. Submerse the hole part in water before you blow into the holes, and you will usually get out a lot of additional media out of it.
Repeat the process multiple times, you can't overclean and it might save you lots of grief and money down the line.
