I don't think cast iron would be any cheaper to port.
Aluminum is a softer, easier to cut metal, so if anything I think the aluminum would be less expensive to port.
Whether or not they can be ported to flow any better than a good aluminum head is debatable I suppose.
I would buy the aluminum head because:
1. They are lighter and can take a good 30-40 lbs of weight off the front end.
2. They are easier to port and polish.
3. They are easier to repair if needed.
4. They dissipate heat better and faster.
