I believe your #1 circle in the photo above may be the valve cover bolt boss? No problem if you break through, but fyi none-the-less.

Yes I think you are correct.

I rewatched the uncle Tony garage porting video and the 318 will run videos on porting. Im trying to understand the different areas of the head as I go. To know where I can remove more and where I need to remove less. It'd be nice to cut one of these in half
