From Allpar.com as well as various other sources:
"As an example of the difference in efficiency, the 1958 354 engine was available in both forms. The Hemi produced 350 horsepower, and the Poly a healthy 310 horsepower. But the Poly is much cheaper and lighter.
Another example, noted by Bill Crews, is the Dodge 270 - a hemi design in 1955, and a less-expensive poly in 1956.
The polyspherical heads were ahead of their time, as were the hemis."
According to Govier, the D500 was a one year, car only Hemi.
