Engine paint, Tips and tricks needed Options

[ThinAir]

I've seen some pretty nice looking Type IV engines here. Often they feature painting the fan housing and intake runners in addition to the sheet metal. Now I know powder coating is the preferred way to go, but I doubt this is a possibility for my project.

So what are your recommendations for prepping these surfaces for paint, whether to use primer and how to choose one, and what type of paint to use?

Thanks in advance for the input!

i forget the name, but i used some rattle can high heat stuff that you're supposed to bake to cure it. i used it on my old rx-7's exhaust heat shields. seemed to stand up to road debris. also, my dad used it on his sportsters jugs.
that was about 4 years ago and it still looks good. no chips or peeling or anything. i'll try to get a brand name.
