This is quite true, on the numbers from the flow bench of just the
carburetors and just the head. I would say, however, that there's a
small advantage in having each carburetor servicing two runners, instead
of three, if only because the runners are straighter, and the pulses
from each carb will be a bit sharper and better-defined with three
carburetors instead of two. Flow numbers aren't everything--they
matter, but so do mixture distribution and mixture uniformity. My guess
is--because of the upper limits on flow of the head--there wouldn't be a
great top-end power increase, but the low- and mid-range performance
would probably improve some, and there would be slight torque
improvement because patchy mixtures delivered to some cylinders would be
reduced.
That said, the difference is going to be small, because of the port
limitations of the cylinder head. Is the improvement worth the money?
That's probably subjective. A hundred bucks a horsepower is pretty dear
for the occasional driver. For the NASCAR guy, it's a bargain.
Dyno comparisons on the same engine would probably tell the tale.
Cheers.
