I used to break rocker arms on my FoMoCo 429 stocker every five or six runs, always an intake (2.25" monster). Had a brand new set of NOS rockers and fulcums cyro'ed three years ago, haven't broken one since. Might also be due to increased spring pressure/shubecks/smith pushrods, but it's worth a shot. Your mileage might vary.
