New Magnum heads for 347 with Flow data

Great work Ramm! Much appreciated. Should make for a real responsive street engine,with low &mid range flow like that.

I'm glad its being appreciated. I feel it's important to not get too caught up and start chasing a flow number. As it is now these flow numbers will support the power goals. However because the air speed is still way too high I may open the pinch further in an attempt to reduce turbulence. J.Rob
