It depends on what head you have, if you have heads with those small slots for the pushrods you can not use self aligning rockers, just use the normal ones...guideplates not even needed. To run guideplates you need screw in studs. If you have heads with large holes for the pushrods and press in studs then you want to get the self aligning ones. If you use those plastic guideplates you won't need hardened pushrods
