500ci street ride, what head to use?

I thought about just opening up the 906`s some more and adding more cam, but I like the idea of losing 40 pounds. When I started researching aluminum bb heads, there are many choices, for example the Eddy Performers, Eddy Victors, Indys and Indy EZ`s, Mopar Stage VI`s, etc. As you read about them, some must have special intakes, offset rockers, changes in port positions, angled plugs, and so forth. A big ported/ big valved 906 in aluminum would be great. I`d like to use my 6 pack induction still ,and I`d like something streetable, that I can use most of my present valvetrain with, (since it`s still quite fresh), compatible with factory configured intake and exhaust positioning , and take advantage of the big cubic inches.
