Highest flowing sbm heads?

Isn't this where the Gen III Hemi can come into play?? The block is strong! And the heads are pretty good as well. And, it's a small block mopar. Wouldn't it be cheaper to obtain 600 hp at a much lesser cost on all motor ?? 6.4 is a monster with just a cam swap - carb intakes out there too. Holley really supports the GenIII hemi swaps

If we talking NA then no, the Hemi is not the answer unless you like big RPM. NA Hemi’s are pigs. This is not unknown but appears to be a mystery in certain circles.

If anyone is unclear on this look at the flow path of air through an in line wedge, the various canted wedge heads and then the Hemi. It should be obvious when look at the flow path.
