Edit Reason: Turley not "Turkey" - bloody spell check!

Hi Steven
I removed the valves and cleaned the valve guides with a special wire brush that fits in an electric drill. They come as a set of different sizes and comprise about ten pieces of wire held in an arc surrounding and in line with the central spindle.
I can't remember now what they're called or where I got them from, but Nick Turley put me onto them.
I would describe the effect they have on the guide bores as "burnishing".
If Nick sees this he may enlighten you. I shall be back in the garage tomorrow and will post a photo.
I think the fit you're looking for is to be able to shift the lightly oiled valve up and down with your little finger. No slop but no tightness anywhere.
