When do you need guideplates?

I am converting my press in stud heads to screw in studs, and most people when doing so start using guideplates as well.

I have comp magnum rail-type rocker arms, that say they arn't for use with guideplates. The rail type rockers will be self aligning, so would i need to run guideplates? If not that would save me having to replace the new pushrods in the motor and buying the guideplates themselves.

Or when converting to screw in studs, do you need guideplates, which meens i need to buy new rocker arms too? or could these rockers be ran with guideplates?

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.
