Magnum Rocker Help

Stock set up is bullet proof . Fairly easy to find at the swaps or facebook . Stock pushrods worked with a reground .480 cam and .028" head gasket . I picked up the entire set up including spider and dog bones at the Garlits swap for $20 .Got a pair of reman magnums off market place for $200. Engintech or melling lifters (i believe they are the same) from rockauto and a china gap intake , runs well.
