The 6.4l is a Hemi. If you look at the Apache cylinder heads, they have the typical rounded chamber with two large valves across from each other. The pistons do not protrude into the heads like some past Hemi designs, but wasn't needed due to the amount of compression Dodge got with a flat top piston.
