I have used brake cylinder dingleberry hones with really good success on lifter bores.
And I bet a lot better than a 3 stone brake cylinder hone, at least the ones with the stones on center pivots. I've observed that a brake cylinder hone's stones will want to tip a bit at an angle as they pop out past the edges of any bore, and that will hone the top and bottom of the bores a tad more than the center. OK for a brake cylinder.... not for a lifter bore; that needs to be kept straight and true.

It might be nice to find an old style hone with the stones fixed in a cylinder, if they are made that small. I hope some of the experienced machinists chime in here.
