Did you try on the engine rebuilding forum? I think most 83 are all alusil (just depends on what they grabbed on the assembly line). They should only need maybe one or two turns with a stone hone to clean them up (just to take the crap off). And that's if there real bad. they just don't ware out. They do score so if you need one or two, used ones are a good options (provided there good ones). Changing compression won't help much without doing other mods. So take a deep breath and relax, that's a pretty bullet proof engine stock.
