Rich, I used Mother's mag and aluminum polish. Here is a link to a guy that did 12 hours worth of polishing with a drill/polishing wheel and and a grinder. The headers shined and actually turned gold. Now his look great. I just don't have 12 hours to do something like that. And like you said, nobody is actually going to see them.
If you read far enough down, you'll actually see that LG...Lou Gigliotti actually commented on them. Nice.
