If you have "rail" type rockers, you don't need/want guide plates.

You don't need guide plates to convert to screw in studs, with rail rockers.

Guide plates are used with standard type rockers. Usually when heads are converted to screw in studs and guide plates. The original factory cast slots are drilled out to allow for higher lift and to keep the pushrods from binding between the guide plates and the factory slots.
