From my understanding, computer designed modifications, completed on a state of the art CNC head porting machine, are able to port a 906 cast iron head to flow similar to a stock 2780559/2468016 cast iron hemi head. 49 years ago, Chrysler achieved what is now achieveable with computers on a 906 head by adopting the Hemi head. No wonder they went the Hemi route.....

Sure, you can put free flowing aluminum heads on that wedge, but again, you can't compare aluminum heads on a wedge to aluminum heads on a Gen II Hemi.

The wedge is a great motor, but it's no Hemi. We may as well be debating a 383 Magnum vs. a 440 Magnum.....
