Have fun driving. Ive had the same thing happen I once
Remember the way this motor is mounted, the crankshaft points towards the back of the car. Therefore you want the cooling fins to be open front to back (like in the picture). Other nitro touring cars i would agree with you on, NT1, CO1, etc, but for the NTC3, this is the correct head placement
