A new Remflex gasket and a little elbow grease and the coach sounds like a luxury hot rod. Wait, it IS a luxury hot rod!
I can see where the PO (or one of his minions) tried to fix the leak with some sealant... talk about a low probability of success...

Does anyone think the exhaust gasses escaping from the middle ports could have caused vapor lock (or something like it?). I went for a couple years without any vapor lock at all, other than one time in stop-and-go traffic at 115 degrees, and then switching on my auxillary fuel pump cleared it up instantly. But I've had an issue where if I have been running down the road at highway speeds, and come to an idle for a couple minutes (which happens regularly at the border patrol stops in Arizona), I get what feels like vapor lock when trying to get back up to speed, at which point everything's fine again. This didn't happen before the exhaust leak developed, so I'm wondering if it's possible that I was just heating my Holley carb a bit more than normal with the leaking exhaust gas.

Definitely would have contributed more heat to the engine room. Everything would get warmer, not just the carb. The fuel pump and fuel lines could also face extra heat if the right side exhaust leaks...

Yes, I actually DID do that. It was at the sand dunes, on an ATV (actually a Honda Odyssey) and we didn't have much choice. It got us through the rest of the weekend.

I'm convinced that vapor lock issues are due more to high engine compartment temps than anything further back such as fuel line and tank temperatures. I normally have no or very slight vapor lock issues. When my fan clutch started acting up, my engine ran warmer than usual but not hot. I had serious vapor lock problems that almost kept me from getting home. When I replaced my fan clutch, all the vapor lock issues went away--even the slight problems I had at altitude in 110F temperatures.
