Did you guys find that "high heat" paint was necessary, or would a regular temperature primer/paint (higher quality like Krylon) be okay?
It didn't even dawn on me that "high heat" paint might be necessary till I happen to lay my hand on one of the vents today after idling for 20 minutes. They get fairly toasty.
Asking cause I'd rather get it right the first time . . . .

Regular paint should be fine.

I have used Marhyde, I believe that's how you spell it, anyways, looks great and stays on good, actually has a picture of a fiero on the can. it works well for any trim that is painted black on our cars

When refinishing aluminum, like intakes and valve covers, this is my 8 Step process. Very resiliant.
1. Strip the old finish.
2. Degrease well and rinse thoroughly.
3. Wash with white vinegar, rinse and dry thoroughly.
4. Spray with Zinc Phosphate primer (used on aircraft) and sun dry for 1 day. Will still be a little soft.
5. Spray with high temp engine paint and sun dry for 1 day.
6. Send the spouse shopping.
7. Preheat oven to 250 and bake on center rack for 30 minutes.
8. Deny the house smells strange.

Thank you, fellas.
Charles, paint type/method aside, do you feel they get hot enough to need the "high heat" stuff?

High Heat paint should not be necessary. You mentioned they were "toasty" after idling..... Check how hot regular dark car paint gets, say on a hood, when it's left in the full sun. Talking about a metal car here, with standard factory paint.

Yeah, I originally tried to re-paint my vents without using a primer. That didn't work out so well.

I think that doing it right would consist of using urethane paint.
That said, I rattle-canned my grilles with cheap spray-bomb clear, and nothing happened during the six months or so the grilles were in daily driver service.
However, I first sandblasted the grilles, so the clear had a good tooth to bite on; it gave a unique look.

John, I've painted others by just cleaning and spraying with regular exterior enamel. Patrick and I graduaded from the same 'done that' class. I don't think it was the heat that made them fade as much as from the sun. The high temp and baking hardens the paint against the elements of nature. Originally, I think they were powder coated. Grills are no easy task to clean and repaint.
