Looking good, those should cleaned up great! ........Look what I'm facing this evening 
With glass bead I was expecting a different finish, different grit perhaps?
Wow, those poor 409 carbs look like they spent time in a lake! What a mess.

Yes glass beading (or other media blasting) can leave a high degree of surface texture/appearance variability depending on the type/size/pressure of the media. I avoid blasting in my process if at all possible but some really rough examples (i.e. these 409 carbs) will require it. In this case its only one of several steps used to revive the factory look (vibratory finisher, sonic cleaner, tumbler, etc.).
You forgot one item !!

No luck on that one jet yet, would not budge this morning even with an easy out in it. When I get home tonight, I might try heating the casting and placing something cold on the jet and see if it pops loose.
Really should have left it alone !

Units are 4758S and 4761S 500's and worked fabulous on my 440.
Question- Does anyone know what the stock jetting is for these two carburetors? I looked everywhere this morning but could find no reference.
They have a lean spot just off idle (not transition but steady throttle) and I want to return them to a baseline before making changes but don't know what the baseline jetting is.

Here is what Edelbrock has listed for the 500cfm AVS knockoff, with single and dual quad listings. That's the way I set my 4966 carbs up with, the engine doesn't go on the dyno for a few weeks. We'll see how close they are then. 
Thanks! I looked at the AFB listings since thats what I'm running, AVS secondaries are very different than the AFB.

Edelbrock has the primary and secondary jets mixed.
Larger jets go on the primary side.

You listed the wrong carb, look up a 500 CFM AFB (performer series).
"Comes with: Metering Jets - Primary .086, Secondary .095; Metering Rods - .065 x .052; Step-Up Spring - orange (5" Hg)"
This is incorrect, I spent hours last night chasing my tail due to it.

Those carbs look great, what did you use to refinish them? 
Glass bead from Tractor Supply, new screws from True Value Hardware, kits and floats from Ebay and gold paint from AC Moore.
