the fact that the fuel line is currently routed over the top of the intake and next to the valve cover is probably a contributing factor

No, probably it is not. Look at the photo below of the rubber fuel line routing in 2511. I think that is exactly how yours is running, from your description. I have zero hot fuel issues. Like Marlin, I live in Central CA where it is HOT in the summer. If that routing was an issue, it would surely be an issue here.

New braided fuel line with insulating wrap running alongside the gas tank, across the engine bay brace and then up to the carb - I hope this doesn't look ugly, but hey, I'd rather lose a few beauty points and save the engine long-term from cylinder wash

Yes, it will be ugly. And not necessary.

Block off the exhaust cross over on the intake

Ford designed the Cleveland with that cross over. They never updated the design as a result of heat problems from it. Blocking it off may lower the carb and fuel temps a bit, but in itself that cross over is not your problem.

Install a 1" riser under the carb - and a smaller diameter but taller air filter

Yes, but like Marlin said, use anything but a metal riser.

New fuel pump

Can't hurt. But what you really might benefit from is a fuel pressure regulator. Holley suggests 4.5 to 6.5 psi.

New plugs - gapped to between .45 and .50

Gap seems large. WHAT plugs? DO NOT use platinum; they foul easily with carbed engines.
