I don't see anything really glaringly wrong with the VE table, but you're idle loads are almost exceeding the idle "zone."

Timing will have an effect on load at idle. If you've seen the engine lean out be reducing the timing, I would continue to go in that direction in small increments. You've got enough cubes and enough compression to soak up the cam you're running. It seems like the timing values you're currently working with aren't making the engine happy. I'd go to 16 degrees and see what that does to both your fueling and measured load. You may also consider bumping the idle rpm up in 100 rpm increments. Both of those things should decrease idle load and may help fuel the engine better.
