360 head choices. What's everyone running?

Personally if I was going to take one out of the box and throw it on I would go with a ProMaxx Head. After having many Edelbrock heads in my hands, my Speedmaster heads, and a Friends ProMaxx Head The ProMaxx looked and flowed the best. The valve job done on the ProMaxx Heads was much nicer.

I hope I'm not hijacking the thread but I've been watching porting videos on youtube. I saw one the other day done by an employee of Edelbrock - was a bit over an hour long I think - anyway he was saying that when you buy their heads that they more or less have to have a porting job on them before you even use them. This really surprised me as I figured to spend that much on them and then before using them, you're supposed to port them too. As you can tell, I'm new to this but I've been reading a lot of articles on "bolt-on" improvements. None of these articles have mentioned doing the port job before using them. So when I saw the post regarding ProMaxx and flowing the best I was wondering if that is out of the box or after getting a port job first? (although I see where it was mentioned to throwing them on straight out of the box) thanks
