Valves: As I noticed you already had the late valves (non-mushroom stems), you may be able to reuse them. Clean them all up with a wire brush to get all the carbon/crap off them.

I would then put them in a lathe and check for straightness, then mic the stems and see what condition they are in and also see that they haven't been reground too many times - having no margin left for a regrind. If the valves look good, then I would polish the stems in the lathe while I was at it. I use some super-fine sandpaper that has already been used on something else - like 600 wet or dry.

Springs: I'd probably pickup a set of springs no mater what - as your engine sat for a long time, had water in it (rust), etc.. The Zephyr springs just have a bit more strength (pressure on the seats) than stock springs. Typically they have about 55 lbs on the seat (at installed height).

Guides: If your guides are good, you can reuse them - might be a good idea to send them to GOSFAST and have him put the bronze liners and seals on them - not a bad idea.
