Cast vs. Aluminum heads and bang for buck..

Now I haven't built a small block mopar in thirty five years so I don't have a dog in this fight but I have refreshed two big blocks in the last five years and both received new valve train. Both have iron heads and both received a little more work in the ports. I personally like working the heads and finding power, I don't go crazy but they seam to work with the 9.5 440 making 520 hp and the 12.5 motor making 645 hp. On the second motor I'm giving up 55 to 60 hp for the price of a pair of Trick Flows less what I spent on valves and springs this last time. I take some satisfaction knowing I'm making the power and not just heating up the card ordering heads.
