Aluminum headed 318s?

Was hoping to find some info out on guys running aluminum heads on a 318. I am doing a Magnum swap now, but my dad really liked the idea of building a 318. We had bought some parts for it, big cam, intake mani, ect. but when I pulled the intake, it had the small port heads. i was told when I bought the car it had the big port heads. So, decided to ditch it. Now, I was thinking someday would be cool to get a good set of heads on it. What combos do you guys run? Saw procomp heads, and other random companys.
