Best heads for Magnum 360

I talked to B3 Racing this week and they say you can run LA-style cylinder heads on a Magnum block with through push rod oiling if you use the correct lifters, push rods (hollow), and rocker arms (i.e. PRW steel rockers). Same concept Trick Flow uses to allow running their heads on a Magnum block, but with rockers that don't cost as much as the HS rockers Trick Flow recommends. My machine shop has a 5.9 Magnum block, gonna talk to them next week about buying it so I have something to put my Speedmaster heads on.
