I wondered how you solved the skinny little
FE valve cover issue! I did find a guy that makes cast valve covers that look something like pent roofs:

Not exactly but a similar feel to them I think. Polished up or even plated (can you plate aluminum?) they would look pretty decent.
There was a guy that was looking for a dual four setup for a cleveland here a short time ago. You should look him up and tell him what you had to go through.
I think for the duals the kick down has to be activated some where closer to the pedal rather than the carb. I will poke around and see if I can find a picture.
