I will help JM out right quick.

Have you done a compression test? If the valves are bad, the piston/rings probably need to be replaced too. If you think they are good, do a leakdown test. Remove the head and pour a little gas on top of each piston and watch and see if it leaks down into the crankcase.

As for replacement parts, partsdinosaur and 3tech performance have what your local NAPA doesn't. You will want to get SS exhaust valves, a new timing belt, and the regular maintenance things for this rebuild. Since you have a 1996, when you go to put the "oil pan gasket" on you need to be careful. Only put on RTV instead of the gasket. You will also want to rent/borrow/buy a 3" ball/berry hone. There is pretty much an entire rebuild (or 12) threads over at GeoMetroForum.com

For high mileage you will want the following things. [no order]
3tech 10* advance gear
3tech economy cam
XFi transmission

I'm sure I missed something.
