New Magnum heads for 347 with Flow data

Numbers will just be numbers unless all heads are tested on the same flow bench.

Quoted for the truth. Alot of people lose sight of this fact. Different flow bench brands can have quite the variance in numbers. Even in the Super Flo line I've seen some fairly wide discrepancies between the 600 and 1020 and from one 1020 to another 1020. People get caught up in the bench racing game too easily, myself included. What really matters is the A to B testing results off the same bench with the same operator.
