I re-read your last couple of posts. Can you confirm that your current two e-bleeds are in the same position as the "old" Holley setup? I'm more familiar with the 5-e-bleed blocks, and am not sure how 4 positions work out WRT the the old Holley setup. That's always a good place to start, regardless.
Since your cruise is so rich, you might have better results lowering the float level below the top e-bleed. That way the top e-bleed will suck air at low main circuit flow. If testing confirms that your engine likes this, you could always move the upper e-bleed to the top position and reset the float level back to the sight plug.
