Does '73 electric choke need exhaust heat crossover in warm climate?

I plan to swap intake manifolds one of these days, 1972 factory small block two barrel manifold/Carter BBD with divorced choke to 1973 factory four barrel manifold/ThermoQuad with divorced/electric choke w/timer thingamajig. Will I have problems with the electric choke not opening all the way if I block the exhaust heat crossover passage? Thank you.
