Stroker intake question and guidance, mainly guidance.

If you were going Carb, I'd say dual plane. The EFI gives me pause to that route though. Single plane you give up lower RPM torque, but does that "rule" remain with EFI, I don't know, plus with a stroker, you can probably afford some.
In the mountains, could you use a little heat below the carb for street driving that you would lose with an Air Gap?
