After all the work you're doing making that engine look purdy, you MUST paint the heads!

I vote for orange, especially with that intake. It'll look killer. But if you leave the heads unpainted, they will start to rust eventually, and that will look even worse than you think it does now. Not painting would not even be an option in my book. IMHO, of course.
Keep after it, you're doing well! Glad to be along for the ride on this one.
