Small block aluminum heads...

Commandos are made by Mopar Performance. I have yet to see one personally, but only hear good about them. There are some unique things tho. Special rockers and stuff for the big port versions. In terms of $$, what do you want to spend? If you're looking for a decent set for under $2000, then the only ones really are Edelbrock LA style. The new Edelbrock Magnum RPM heads look decent too, but are also untried. With a turbo, I'd think the bigger the better. The Indys are a good head, and while look more expensive, come as a kit. So the intake, pushrods, rockers, and hardware are included. The lowest level deal would be a set of the Indy Edelbrocks with the revised intake port. I think Mancini has them for under $2500 as a complete kit. You may want to talk to them tho,the valves and springs may not be up to what you want to do.
