Wow, I would have never guess that at all.Yes, that can be added. And not only that, but ALL PI heads are the same.. as in there is no right or left. The castings are identical. They don't become "right or left" until the cam, the tensioner, and other bolt on items are added. So they can be swapped right to left easily.
Thanks for all the info, guys. I'll be using this article A LOT throughout the next few weeks
