Neil did my valve guides. Back when I sent him my parts, I shipped him a set of new valve guides that I acquired in a rebuild kit. He indicated that he preferred to use his own guides (which I agreed to), as loose guides can cause all sorts of problems including noise, and he wasn't familiar with the ones I provided.
