Before having it machined you should ask if they will be providing bearings. I actually recommend buying a reground and using yours as a core. It will come with new bearings. Just make sure you really clean the oil galleys out VERY well. Use carb cleaner, compressed air, and a gun cleaning kit. And check all the clearances, the mains are quik because you can check them all together by putting plastigauge on each main then torqueing the main girdle. The rods you do one by one. Its not bad though because at that point you should be installing new rings so it slows you down. Going slow is a good thing because you can keep a clear head and think about everything you are doing carfully.
