Magnum Rocker Help

What is the most cost effective rocker arm setup for a Magnum 318? For little money I bought a long block minus any of the rocker arms and their associated hardware. I'm putting in a mild Hughes steamroller cam and their recommended valve springs/retainers/locks. I'd like to go with stock rockers, but I can't find kits. I found the rockers but not the other hardware. If you know part numbers please pass along. Thanks!
