Performer RPM or Magnum Heads

Heres the deal... I bought a set of magnum heads from a junk yard off of a durango. I sent them to the machine shop and had them freshened up. I was then thinking about getting a set of aluminum heads.. So i sold my iron heads.. I bought the M1 magnum intake but i could always sell that. I just want to know which heads will wor better on my procharged small block..

Also the magnums use small block chevy rockers with are cheap.
