Quote, "Again, Thanks for all of your ideas and cautions about the little 283 and it's limitations. I'm going to be taking it to a machine shop to have the machining done and I would like to have an idea of what I'm looking to have done so I don't get the Machine shop guy's favorite build instead if what I want done."

At the machine shop, ask them to first measure the block so you can both review where the wear is, main bearing alignment, of course cylinder wear and taper, also is the deck square to the crank, it may need a slight cut to clean and square the deck. Since your doing a "more stock" rebuild, as long as the mains are in tolerance, you can skip align boring, cylinder taper and wear will most certainly need addressing. I'd only go over bore sized to clean up the cylinders, no need to max out the diameter, plus it costs money to continue cutting. The cylinder heads should follow the same procedure. Ask them to measure and evaluate so you can both review what the process will be to rebuild them. Guides are probably worn, and probably the valve stems... the seats? If they are damaged you'll have to make some decisions! They'll probably need to have a cut to flatten them again.. As long as you tell the machine shop what it is you're after, they'll try and work with you I'm sure, plus they can help guide you to what will be most cost effective. Just be honest with them and tell'em what you're after I'm sure they'll be glad to help.
