Question for Super Stock Thermoquad racers

Is there anyone on FABO or know someone who is running a 72 to 76 NHRA Super Stock 340 or 360 A body, would like to know what mods you did to your Thermoquad to feed enough fuel through the single inlet to the 2 sets of needles and seats to keep an ample enough fuel in the bowls in order to stop the engine from leaning out going down the track? Have tried larger needles and seats more fuel pressure, air door adjustments, larger jets. Just can't seem to keep enough fuel flowing through the carb to feed the engine. Any help will be much appreciated, Thank You
