Well here's the answer. They are metal rods that go in the block. During the casting process, they are in the block to hold the casting as it goes down the line. If you have your freeze plugs out, you will be able to see them around the corner. They are later cut off as they would stick up out of the deck but the main part that runs through the block is still left in it.
I didn't think anyone would get that one. I told you it was a tuffy.
