Hank, If velocity does not increase why divide the intake manifold ?
A divided intake port has a choke area that will support a 292 at 6000 RPM and a 250 at 7000 RPM before VE will fall off, with a mach index of 0.54 and 0.46 respectfully.
air flow numbers with a divided head will support about 300+ HP
Just food for thought, Harry
