Headers

A friend of mine and I were discussing if it's worth the extra money for ceramic coated headers. He said no and I said that from all of the information I can find out is that headers that are ceramic coated help keep underwood temperatures down by keeping the heat in the combustion chamber were it belongs. So, is it worth the extra money for ceramic coated headers? For a sbm it's around $250 or so. I thought that it would be best to ask the guys who actually have experience with headers instead of what some magazine may have to say especially since they are trying to sell the product.
