Push rod length will have zero effect on the roller tip to valve stem relationship because its a rocker shaft system. You will have to run lash caps which will lengthen the valves and that will move the roller closer to the shaft side. But to run lash caps you have to have enough room at the top of the valve stem which means you may have to change your locks and possibly your retainers. Here is a picture of rocker arm geometry:
