it helps to support the cylnders because of the block being a open-deck degisn, unlike others that are closed/semi-closed decks that are much stronger this aids in strength.

Yes the shop that built my motor installed the block guard. It has nothing to do with oil flow, it’s the coolant area above the water jacket where it goes. They installed the guard (from what the guy said) by just placing it in place and finishing it off by SLIGHTLY taping it into place with what I don’t know. Then the block was decked for a good match with the head of course!

That looks pretty strange, your BG is not deep enough, it may block coolant flow. It should fit around 6...7mm (1/4") below deck surface. And btw, Golden Eagle FTW, best BG design I've seen!

Here's mine;

^So is the sides of the guard tapered or is the coolant cyl walls tapered? I guess my question is how does it not fall into the coolant passages w/o welding it in or something?

Those tips in BG between cylinders are tapered, so are aluminum casting around cylinder sleeves, so that "locks" BG to lowest possible position. Here is excellent picture to illustrate it;
