Head and cam selection help for 440

This isnt something im going to do tomorrow, but i want to have a plan put together so i can start working on getting the parts. If its is best to go with the aftermarket heads, i need to figure out if i can do either open or closed and what different options i have so i can be looking for deals or maybe even a good used set..or if im staying iron, i need to be planning the parts for that..also, if staying iron, i have to figure out how to ship the heavy things to a porter without spending more on the shipping than i do on the work on them..
I wouldn't even think about porting those iron heads. That is the least cost efficient way to go. What Dwayne is saying research the cost of what you will spend on parts less the heads. Then what you have left you budget for your heads.
