Move to 45 pilots for the popping, check for leaks on the little rubber vacuum caps, at the header flange to the head, and the slip on joint and take out the shims. Balance and sync the carbs. Get a dyno and go from there.

The 45 will help your idle circuit, the TBS's will take out that mid throttle dip.
