Yes the valves and springs are smaller, but now you have twice as many and I
think if you actually weight the valve and spring packages you would find
that the 4 out weight the 2. Now add into the fact that you have heavier
rocker arms and the recip weight goes up. Where the actually gain would come
in is like Dave said eliminate the pushrods and rockers. Little know fact
every major car manufacturer has abandon pushrods except one.  Dave as far
as flow I looked at the docs for the Ford and Chevy heads. Ok lets take the
best heads their C3 version. In the Fords case it was compared to a
Victor/Gliden head max flows were 396/313 vs 365/242. For the Chevy it was
compared to a Brodex-12SP flows were 389/303 vs 378/246.  I just don't see
these heads being the magic wand of Horsepower. The cost is about the same
as a great set of 2 valve heads with maybe a slight gain in HP, but not RPM
capabilities.
