intake/exhaust mounting, what am I missing?

Won't be terribly long I'll be installing my intake/exhaust manifolds. I'm just wondering if I have everything(bolt wise, etc) some of the studs are shorter. What do I need and is there How to for installation?
As always, a big :thankyou:

Of course I still need to clean them up
