It comes down to the basic mechanical common sense, once you take something apart and put it together will it ever be the same??? NOPE, it will be very close to it but not the same.
Agree...

Ever heard of blueprinting? That's where a shop takes an OEM engine apart and then builds it the way it should have been done in the first place.

BTW, the big difference between a stock engine and a built engine is the pistons. Built engines have forged pistons while stock is cast. Forged pistons, while stronger, have more thermo expansion and therefore require larger clearances. Larger clearances mean shorter engine life before the engine becomes an oil burner. If looking for long engine life you will use cast pistons that are carefully fitted.
