I got a roll of 3in by 50ft of fiberglass woven fiber today and was thinking about using it as header wrap. Anyone ever heard of using fiberglass as header wrap before? I'm not sure what the after market stuff is made of. Do you think it would burn off? I just made up some spark plug boot covers out of it and that didn't burn off just driving around. But I know that the temp differential between the plugs and actual header has to be alot.
