By the way, big thanks to the good folks at slantsix.org for all their help so far. I've also relied on the Super Six article posted there, which has all the info you need for this job. I'm posting this thread here instead, mainly because it's so much easier to post photos here.
Once I got the manifolds separated, it was time to remove the carburetor. The first thing I thought was odd is that it has 2 bolts holding it down and two studs with nuts (is this normal?). The bolts came out fairly easily, but one of the nuts required vice grips and all my patience.

I also spent some time trying to remove the vacuum connector on the #6 runner, as well as the Charge Temperature Switch (part of EGR control). Eventually I decided to leave them in place, though I won't be using the switch. I do want to have EGR working, but as this switch works with the EGR timer system which I don't have, I could remove it. If you know how to get it out of the manifold, let me know. The hex seems to be nylon, and it was starting to break before coming loose.
