Cold weather leans out the mixture but it shouldn't be enough to make them glow red at the collector, but I'm no expert. Do you have an AAR? I have one and it kicks off high idle after 10-15 seconds in the summer and maybe 30-40 seconds in colder weather like yours. Maybe because it idled so long at a high rpm - combined with SS headers and a leaner mixture - that might be it. Is there a way to adjust the AAR? That seems like way too much high idle time. Might be a small air leak too. Retarded timing can raise exhaust temps too so maybe double check your distributor/timing.

I think Steve Weiner posted some shots of a 935 (1.5bar)dyno pull where you could almost see the turbine blades - white hot.
