Well that would depend on how much boost you are running and the quality of intercooler (I'm assuming an intercooler, closest thing to a free lunch!)
In theory poor flowing heads will raise charge temp because more boost (air compression) will be required to hit your hp target or goal. In reality intercooler choice, boost level and turbo selection will have larger impact on charge air temp then the heads IMHO. Maximizing your air density pays off handsomely whether you have ported heads or not.
At 35 psi the relaint with an air to air unit would be at ambient or slightly below that at the end of the track according to the datalogger.
Nothing like 4 cores and airflow at 130 mph to cool things off.
