I am not against using the stock pistons if they are in good shape - especially as it seems that is a good way to go (from what I am reading here).
It has its advantages.... But that ought to be judged from a teardown and bore/piston measurements. If the bores are worn, out-of-round and tapered, and worn pistons, then you'll end up with an engine with a lot of blow-by and more limited life. Good piston-bore fit is one of the fundamentals of a good running engine.
