Unfortunately, or fortunately, depending on your perspective, the Trick Flows use LA valve gear only. The rocker is the key to the head working on a Magnum block, just like any other Magnum/LA head conversion. Geometry is much less of a hassle with the Trick Flow head though, especially with certain rockers.What BR3 said
stock magnum rockers work unusually well for stock rockers
still have to set the fulcrum height with a big cam or long valves, etc
