AFAIK, the hemi also has dual ignition. On early versions, each double-legged coil shared a wasted spark with a cylinder 360* away in the firing order, so that if a coil went bad, all cylinders would still fire. I don't know if this is still done on later versions.
they are thru atleast 05... . this one also has two compression bent connecting rods, indicating that it unsuccessfully attempted to compress some liquid... probably antifreeze...
