OH NO!!!! Valve guides

Posted by Farmwrench on February 21, 2005 at 05:39:55 from (205.188.117.7):

Started to get into my late Grandfather's Avery V. Every thing has looked good. No stuck bolts. Next to no rust. (12 different colors of paint and 1/2" of hardened oil soaked dirt everywhere!) NO sign of a ridge, pitting scouring or other bad things on the cylinder bore! Rods are tight. Valve sealing face is not pitted/burned and not worn enough to see light between a razor on the face. But the stems are worn 1/2-2 thou and irregular wear The guides are 8thou over in the middle!!!
THis has a Hercules ZXB-3 Guides are replaceable 1/4" nominal ID. I don't want to take the engine out ofthe frame if I can help it. I have access to valve grinders and seat grinders. I have a lathe (made a new shaft for the govener the day before).
1. Why were the guides so bad and everything else looking ok?
2. Where can I get a set of new valves and guides? Guess on $
3. I think I now a guy with a centerless grinder that could recondition the valve stems and then I could machine up new guides (bronze or Iron?)with undersize bores to press in and then ream to size.
What do you guys think?
