But these guys are adding noindex along with nofollow on About and Contact pages.
Noindex makes sense on that type of page, nofollow does not. It used to work towards sculpting pagerank but it's no longer effective at that so I would stick with noindex only.
I wouldn't nofollow the link home either, which is what I assume you mean by "the header", unless you have another link home elsewhere on the page.
