I would retrace my steps, verify every water pump bolt is in the correct position. Maybe look at some unposted pics of your engine to help determine if there was something else there, like a bracket or sleeve. You'll get there. I would leave the starter and the drag link off, your header install will thank you! Also, if you think the water pump was fun, stand-by for the header install!

late thoughts.... could that long bolt belong to your power steering pump?
