After removing the air injection system, checking the valves after 54K miles, and changing the pilot jets/shimming the needles, just stuck (literally) the carbs in place so I could fire the bike up long enough to see if I had any obvious leaks around the valve cover and carb bowls. I had pulled the air box for repair because I noticed that the bottom seam showed signs of separation, so getting the carbs on for this exercise was a piece of cake. The air box has been repaired.
Will pull the plug caps tomorrow to check further in the pockets, but for now, no obvious external leaks.
EDIT: I can see it when looking at the bike, but the pix make it more obvious that I need to get some silver paint and touch up the caps on the carb plugs to make them more "presentable." I could have soda blasted them, but decided against it. Dhoo!
