New Magnum heads for 347 with Flow data

I didn't post in this thread to be a jerk, but when people who know better blow off facts or another's factual points...why should I not do the same in return.

Do you believe the factory magnum int port has an advantage over the old 360 port?
I believe on a 318 magnum is that in the middle better choice for a street car needing a lil more power but isn't looking for or all out.
But the 318 port is 125 and this magnum is 153 cc, so whats 7 cc?lol

I agree with you also on intake manifold runners and sizing for ...air speed and the response/torque from it.
