440 cylinder head opinions?

There are a lot of cylinder head choices these days. I was over at the engine shop yesterday and they are finishing up a 383 stroker with the 75 cc Edelbrock RPM heads. They also had a motor going together for the new Trick Flow heads, one with older Edelbrock 84 cc heads and one with Indy EZ heads. I think there were even a couple of cast iron head motors there.
