I believe it varies with the powder, there is no "standard" (except they have to withstand the cure temp obviously). Eastwood and Caswell both sell powders that are good to 1000F and go on just like the lower temp powders.
I've got some from another source that is supposed to be good to 1200F, but haven't put it to the test yet.

I didn't go the powder coating route but used the POR-15 product. My manifold was really ugly but here's how it looks now

Randall, thanks and that makes sense that it would depend on the quality of the powder. I saw that eastwood has the 1000F powder, I'm just anxious and want to get the care back together this weekend. I suppose I could try the lesser and see if there are consequences later.

Soup,
As you can tell from my web site, I like Dupli-Color 1200 Degree Ceramic paint. I was bored this past weekend and did my original exhaust manifold so I can wrap it up and put it away.
The red paint has held up fabulously on my block.
EDIT: I forgot to state that this rusty manifold was grit blasted and acetone washed before painting the silver.

Peter,
I never did any of that except to run the engine after painting. Oh well, I got lucky!! However, per the instruction, I painted in several layers and I DID wait for the seven (7) days for the paint to cure. The block was perfectly clean and washed down with acetone prior to painting.
But it really did smell like burning plastic though when we were running the 20 minute break in cycle.
I really don't think that I'm going to tell my wife that I need to use the oven for a few hours to cure the manifold. The next owner can handle that process.

Paul - thanks for the input. I have decided to paint the manifold instead of powder coating it. Recently, I thought I would by a paint product sold by a wood stove dealer. I haven't stopped into one yet but plan to tomorrow and would think they would have something. However, the Dupli-Color does look like a real good option, just hate the seven day cure time and know I couldn't stick that baby in my wifes new oven (on the plus side it is supposed to be hot as an oven this weekend).
Paul, where did you get your Dupli-Color? I'll do a web search also.
PS: the manifold is being sand blasted and hopefully ready for pick up tomorrow.

Soup,
Tap the stud internal threads or run a die over the installed studs AFTER you finish the painting and well after it dries so that the cutting oil doesn't affect it.
I bought mine at an Auto Zone. About $5.00 per can. I'd put the three coats on per the directions, let it sit all day in the sun exposing each side for several hours and install it a day or so later. You'll be able to tell by touch if it's ready to be handled and the sun will speed the drying up a lot.

<div class="ubbcode-block"><div class="ubbcode-header">Quote:]was it wise to do the gasket as well?[/QUOTE]
I think that question may be directed to me. I did not do the gasket. It has a very shiny metal finish from the manufacturer. I just had it there so that when I chased the threads and installed the new studs, I would put it on the flange before I packed it up.
Less chance of me losing it that way.

got out of work early, picked up manifold, Dupli-Color, acetone and went to work. I put an old windex pump sprayer into the acetone container and hit the manifold up pretty hard (the stuff evaporates quick). Let it dry for a while and started painting per the directions (3 coats about ten min apart).

The longer you let it sit in the hot sun, the harder the paint becomes as it cures. Nice job!! One or two days and you should be good to go.
Note: The key as always, is moderate layers, but applied in the time frame and then just let it sit and cure.
The machine shop had to acid dip my original Dupli-Color painted head twice to get the paint off of it, so it will last if done properly.

It's the sitting around and do nothing part that is tuff. I had four exhaust ports with plow by so I am anxious about how she'll run, sound and look. I say look because I had the intake, valve cover, and air cleaner all powder coatd and picked them up as well (no pictures yet).
