ICON makes 3 different(20.5, 27, & 34 cc) dished pistons specifically for the magnum (1.445 C.H.). They also make a domed, a dished(20.5 cc) and a flat top in the regular LA 1.465 C.H. Just kinda depends on what heads you have and what compression you want. CNC has em pretty reasonable.
I'm watching for an LA "roller" or magnum block myself...
