No, it's bogus. Somebody cobbed it with what they had laying around in the shop. You really need to use the correct studs, flat washers, and nuts. The studs need to be the right length. Too short, and you can't get enough of the nut on, too long and you can't get the manifold to clear.

But I will say that the world will not end if you use a couple of studs to position it, and use bolts for the rest. Just make sure the bolts are the right length. Either way, dont forget the flat washers.

I believe that the exhaust studs are different from the intake.

You can make the hose from the air cleaner to the intake from fuel line or PS hose or even heater hose. It's kind of tricky getting the length right because it needs to be a bit (maybe an inch) too long so that you can connect it as you install the air cleaner.
