Interesting heads!

MOPAR ran an even more complex setup in their "Six Pack", three two barrel carbs. I think Pontiac beat them to the punch with their early 389 Tri-Power, and Chevy used it on the L88 427. Interestingly, MOPAR did not sell a 302 powered anything, their homologation car had a 340 Six Pack in it, the T/A Challenger and the AAR 'Cuda. They had to de-stroke it to make the 5.0 liter limit.
I'm pretty sure that you are right with regards to both simplicity and power. Modern single four barrel setups flow very, very well (thanks, NASCAR), and provide all of the CFM's a high revving 302 would ever need.
The dead giveaway on Smokey's hemi heads is the exhaust port spacing. Rather than the two center ports on each side being virtually siamesed, they are evenly spaced, like on a big block, or on a Chrysler Hemi.
