From what I understand of the 914 heating system, the fan housing outlets have to be blocked off if I'm not running heat. Can anyone give suggestions on how to block these off? I could weld them up, but Im not sure about the material, and I'd like to be able to seperate the fan housing without grinding and rewelding.

But here's the thing nobody's mentioned. There are flapper doors on those ports from the factory. Those port are blown open by the cooling fan most of the time. The flappers are there so that when you turn on the supplementary heater blower (electric one in the engine bay) those flappers are forced closed by the increased pressure on the HE side. So are we saying that turning on the heater fan in a stock car will overheat the motor because the flaps are closed? I find that hard to believe.
