According to the machine shop I have 5 bad exhaust valves on my motor (65 300) and two bad seats(or was it guides, I don't remember what my dad told me) that they are going to knurl. Any body know where I can find 5 new valves for a reasonable price? Machine shop says they are difficult to find. I had a feeling I was getting in over my head by having a "simple" valve job done. Thanks, Philip
