Head and cam selection help for 440

Before you get too excited about those SM heads...... do your homework on them.

The cnc version is ported.
oh im not sold on those or any other one, thats why im here asking for help..lol..all i know about those heads is that apparently they had one heck of a sale that i missed out on and i believe remember seeing that you are better off buying them bare and using better hardware..Like i said, i would LOVE the trickflows, but not sure yet if i can, so thats why im asking about all the rest, speedmaster, promaxx, edelbrock, 440 source, and whatever else is out there..and i also watch the for sale section in case something comes up there, but i need to know more before i do anything, like do i need to stick with open chambers or could i go with the 78 cc closed chambers with my pistons.
