Ooh, probably a bad idea.   Header wrap works, but it makes your headers 
disposable.   It traps the heat inside and literally cooks the metal at the 
molecular level.   Works fine for roundy-round racers that buy their headers 
for $100 a set and throw them away at the end of the season, but definitely 
not smart on something expensive like your 180s that you're trying to 
preserve.

Either ceramic coat them, or just leave them alone....
