aluminium head questions

If I can find a CNC ported version of the MP heads I'll probably go for them. The off-brand, China made stigma of the Steath heads has me a little worried. However, I haven't found a ported version of the Mopar head yet. Does anyone know where I can find one?

Also, what intake/carb combo would be best for this setup? I'm partial to the looks and nostalgia of the 6 pack setup but if I'm leaving HP's on the table I'm up for a change. I think I'd perfer low end torque over high end HP.

I haven't seen exhaust flow #'s on the stage VI's but I'll keep looking.
