Stock magnum bottom end with tricj flow heads what cam?

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
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.
