->idea...  It was my mothers...  Yay mom!
->
        Ah, yes, mothers are the necessity of invention.


->. The cam is shot.  Mostly the lobes are pitted, just plain ugly.
->Anyone got suggestions for a replacement?  I'm not interested in
->something like a roller cam, but something with a *little* more lift
->might be attractive..  :-) My machine shop says that they can fix the
->old one.  Anyone have that kind of work done?  Can I believe them?
->
        Replace it. The S2 cam is available from TS imports for $125 + core.
It's a nice race/street cam.

->. Some of the tappets are badly pitted too.  Can I just replace the
->pitted ones? 
        I had the same problem, but the pitted ones were randomly scattered.
@ 4.65 ea, isn't it worth replacing them all? I did and am very happy about it.

->. My machine shop says that I can't put in new valve guides without a
->press?  Is that true?  Any tricks I should know about?  They also
->suggest that they rebuild the head, not me.  Uh, I feel like I could
->do it, but then again I've never done it so... Have any of you guys
->rebuild a head in your garage?  (or in the kitchen sink for that
->matter... ;-)

        I did it in my garage. But then my garage has a press. And you do need
a press or something like it. You'll need a .3115 ream as well. And a valve 
seat grinder pilot. I sunk ~$50 into tools for something the shop wanted to 
charge me $45 to do. Your call. The work is easy, but does require some
specialized tools.

->. I would like to raise the compression on this engine just a tad.
->Stock it's at 7.75, and I'd like to see 8.5 like the earlier engines.
->Am I being stupid, or is this a good idea?
->
        Again, easy to do, but don't take it too high without a good look
at your pistons.....

->BTW does anyone know how to remove grease from a sun keyboard?  :-)
->
        Don't try windex....Your kbd will never function again!
(take it from a former FE)
