if they are self aligning than you do not need guide plates, if they are non self aligning than yes you do need guide plates and hardened pushrods

The only way to tell for sure is to try. Most do require some trimming.

Also, are they wide-bodied or narrow-bodied rockers? You may have issues getting wide-bodied rockers to fit properly - LT1s use narrow-body rockers.

Since they are non self-aligning, you will need HARDENED pushrods and HARDENED guideplates.
