With modern aftermarket heads, is there a distinct advantage to the hemi now? From my limited understanding, flow was the major advantage to the hemi over the wedge.
You mean modern aftermarket heads for the Baby, the Elephant, or the "I-wish-I-was-a-Hemi" modern 5.7/6.1/6.4L?
The best advantage would be 4 valves per cylinder like the imports and a mild dished piston with a quench ring on the perimeter. There is too much dead space and area for thermal transfer on the older Hemi stuff. They still make good power - but it's an old (like 1920s) design that ignores a lot.
Ever heard of the Covalt Hemi? that's one I would love to have.
