I thought that as a rule overhaulers listed exactly which parts went into
each engine. Mind, my experience is limited to one overhauler (Pacific
Continental Engines) and one engine (mine: O-360-A4A). I did not have
the engine overhauled, but the build sheet came with the airplane when I
bought it. It listed by manufacturer (Lyc, Superior, etc) and part number
just about every component in the engine. With this I have been able to
avoid AD notes on piston pins, con rod bolts, fuel pumps, etc.
