There is a special, high-temp paint that you can buy. It works great on applications like this, as well as valve covers. To answer the question your thinking of right now of "Do they have CHROME high-temp paint?" Well, yes they do. I've seen it at local super markets and most automotive parts stores should carry it. To explain what the warning on your paint says is when it says it flammable, it means not to expose to OPEN flame. If it gets hot, it wont catch fire because once the paint is out of the can, it is not pressurized which means it is not able to combust. Good luck, post some pics up of it when your done.
