When I first start my '71 LT-1, if I haven't driven it for awhile (several months), the headlights will pop-up, without me touching the switch. After a few minutes running, they will go back down, and work properly thereafter.

Is this just because the vacuum hasn't been "held" in the cannisters, or might there be a problem that needs fixing.

Mine will do that on occasion also.  I have completely rebuilt the headlight system with all new parts so it must be related to the lack of vacuum in the system after sitting. 
 
I tell my woman that she is just giving me those bedroon (drive me) eyes.

There is a check valve and filter that is located near the distributor on the drivers side. Change thes and it should solve the problem....hopefully.
