It's hard to see with this photo but evident with the naked one. I didn't see it at first until the machinist pointed right to it. He also has a BMW, and even has the same head in the shop for a customer. Then his assistant walked out and even before looking at it stated that it must be one of the center cylinders because it's common on these heads. So no, it wasn't pressure tested just visually, it's there believe me.
