The pictures will help a bunch, but not quite enough (yet).
There is one that needs a retake as you only caught what looks like one of the digits in the engine block casting code (see picture #3). You need to look at the spot in between those 3 bolt bosses and the number you seek should be there. Helpful hint: if you rub the spot with a piece of chalk, it will help highlight the raised casting numbers and make them easier to see and read.
To help you locate your engine block casting number, take a look at the below pic (red circled area) on where to look on your engine to find that number.
