I noticed that the 354 DP heads are machined out to a full Hemi chamber. The article says they are based on the 6.4L "Big Gas" truck heads. From what I could find on those the chambers, they are more oval with small quench pads on each side. They show the chambers in the video around 2:30.

I searched in the forums but did not find anything. Anyone seen or flowed these heads?
