How a B3 kit impacts the valve lift is dependent upon the rocker arm's dimensions & geometry. This pic shows a T&D on the left and a Hughes on the right. If you look at the respective locations & angles of the lash adjuster screws, you may understand how moving the rocker arm up and / or away from the original pedestal location can change the lift curve more on some rockers than others. It's one of those factors that you only know for sure by plotting the lift curves with and without the relocation kit in place.
