Yes, that is a '67 intake with the heat chamber/crossover that wasn't used in '66.
As suggested you should be able to block it off with a steel shim/gasket.

Would it be better to block it off from the bottom of the intake? Between the two manifolds?

And, if it was made this way, what kept this from overheating all carbs?

Question

Looking again at your pic of the carb it appears you have a '67 carb.
If so are you using a '67 base gasket?

Yes, and this is what it did after 5 or so minutes.

This passage is a Factory design for cold start.
What condition is the Exhaust Heat Control Gate/Valve?

Seems/Looks like it may not be opening up upon warm-up.

After blocking off the exhaust ports in the intake we got it to run long enough to do the break-in!

Jeff is right on point about the valve in the front 1/2 of the manifold.
If you can’t get it to work right with the bimetallic spring you might be able to remove it Or wire it in the open position.

The valve was not working correctly even before we got it running, so the spring has been removed and the valve hung in the open position. The combination of that and blocking off the exhaust crossover in the intake has made all the difference in the world.

After figuring out that two of the followers were made wrong and hanging both the intake and exhaust valves open on #2 (and fixing that issue) it's now hitting on all six and running great! Finally took it for a spin last night and, while there's still a little timing work to be done, she's a strong engine. Couldn't be happier with the end result thus far! It's been one hell of a journey but totally worth it in my opinion

Neat Project.
Just curious as to what do you have planned for the rest of it?

Mike, the eventual plan is to clear coat the exterior and completely restore the interior. Other than that, just drive it and have fun

Well, been a while... I've got about 2500 miles on the engine now and decided to install a Holley Quadrajet Sniper system on it. I'm still getting the kinks worked out of the system but, all in all, it's working well now. I'll get some pics uploaded this weekend.
