 Well, my 907 is not doing so hot.  All of my exhaust valves are too tight, and three of the valves need shims less than .060" in thickness, which the shop manual says is a no-no.  Delta also told me that the smallest shims they stock are .064", and I have six valves that need smaller shims than that.

So, what am I to do?  Do I need to pull the head and take it to a machine shop for new valve seats?  I'm not sure exactly how to proceed, since I've never fallen below the minimum clearance on a valve adjustment before ('course all previous ones were on an old VW 1600 cc engine).

I'm tight on cash this year because we just bought a house, so I'm trying to find the solution that is cheapest without being 'wrong.'  That is, I don't want to patch things up and have to do them again later; I'll let her sit through the summer rather than cutting corners.

I have access to a machine shop here on campus, too, so I might be able to do some of the work myself, if it's not too complicated.
What should I do next?

Thanks,
Edward
