IIRC... the factory six had different heater control valves (the flapper box thingie) that had a hole in the end. I don't know what it was for, but I do know that Porsche discontinued them really early in the parts program and substituted the four cylinder ones as replacement parts.
ok, now we *need* pictures as i'm pretty sure my '70 /4 flappers have holes in them as well ...

The picts suck, but PET lists a different part numbers dependending on if it is a six or a four.
