I did not intentionally disassemble the pistons from the bore, but on one of the cylinders, the pistons stuck to the thrust plate and they did come out. Are they matched like a lifter to its bore from wear, or were they matched at the factory based on tolerance?

Nothing like a lifter to bore. Or a piston to a sleeve.... No, MUCH tighter than that. They are sized to the bore at the factory. If you take one out of it's hole, hold it in your hand to warm up.... It won't go back in the hole you just took it out of. The only thing close to the tolerance of this is inside a diesel injection pump. You can put them back in... but the hydro may not last long. If your lucky, they will have enough wear on them they will be ok. But, don't be surprised if it fails.
