You have to make some exhaust flanges that except a banshee style pipe. You can use the fmf's but you have to put some dents in them to clear the power valves, paul turner pipes fit with no problem. The pump can be removed and a block off plate from a banshee can be bolted on. If you want to keep the lower geared transmission put the rz jugs, wiring on your lower end. I'm running a complete rz motor, the gears are spaced a little higher. If you plan on doing a full engine overhaul, get a banshee transmission off of ebay and stick it in. That way you can keep your other banshee motor complete.
