Header paint
If it is out of your price range though, any 1300-2000 degree paint can work. Either a good hardware store or an auto parts store will have it. The problem is that to fully work you have to cure them which means having an over to fit them in and that will heat to 600 degrees.
Some header paint can be cured on your vehicle, but it won't be as good as through an oven. As such, powder coating would be the best bet.
at that point though its almost work the extra for the ceramic coated ones or powder coating them.
