You should consider running a bypass regulator that will constantly circulate the fuel from the tank to the regulator. If the regulator is placed near the carb, there should be no problem w/fuel percolation.

I'm going to guess you are already using an insulator between the carb and intake. You could also try blocking the heat crossover under the plenum. Use a good quality mechanical fuel pump.
