Hello Joe,
The feed is generated in the /components/com_k2/views/itemlist/view.feed.php
The description of the item is the <description> cell of the feed. It is generated in the item model.
The classes are defined inside the models as well.
/components/com_k2/models/item.php and components/com_k2/itemlist.php
I would not hack these files because since they cannot be overridden, you will lose your changes when you update.
