We usually mill the slot in the large piston letting it sit further out in bore so the cup doesn't overlap the miss-drilled porting (and leak) in those "high" quality wheel cylinders.
If you compare the location of the hole in your old wheel cylinder with the new ones; you should be able to see if you rec'd the better parts.
