These are details of an engine head from a Dodge 2.0L SOHC engine. It came off a testbed vehicle that included the Magnum's active intake, but I believe it is not the Magnum head.

I noticed upon close inspection that this head had mild port work done on the exhaust side before it came into my possession.
 
Here, you can see the casting date on the head, as well as an inscribed number that I can only assume means something to the guys that were testing this.
