If it's only right at the top of the piston, don't worry about it if it is small. Ive filed to edge of a piston because of a few small nicks and it ran perfectly after that. Only if there was a scratch going down the whole side of the piston, then you would replace the whole thing as it wouldn't hold the pressure.
