Fuel Line Mod Done - Still Having Hot Restart Issues

That does make a lot of sense. One time last week, I had just restarted it after it sitting for maybe 10 minutes, and of course it was hard to restart, idled erratically after finally starting. I drove 2 blocks, and as I sat at the stop sign, it died. When I went to crank it, damn if I didn't flood the thing somehow.

Also typical of percolation.

If memory serves me correctly, in asking the guy at Daytona about if it came with a float, I think he said that the 1920 comes OE with a foam float, but what we want to use is a brass replacement, right?

There's no brass float for the 1920. Use a new foam float, Walker number 100-14.

Also make sure your manifold heat control valve is free and not stuck. With the engine cold, grab the ~3" round disc facing front on the central collector portion of the exhaust manifold. Rotate it counterclockwise til it stops, then let go of it. It should spring back clockwise. If you cannot turn it, or if it is stiff and doesn't spring back, hit it with Mopar solvent number 4318039AC.
