I'd say ceramic coating would be the best, it would give you the absolute best finish possible. As for painting it, I'd say either leave it be nice stainless looks real nice. Sure it discolours a little, but it beats the look of paint that is flakeing off or burnt.

BUT if you do paint it and it burns off, you can always get them ceramic coated. I think fireball charges like $150 to coat a long header.
