Since your manifold doesn't have super long runners that would add to the stress, I would say you don't need a brace. People running long tube Top Speed manifolds don't need braces and they're fine. I ran that kind of setup for a couple thousand miles, no probs.

If you want peace of mind, you could have a support welded from the turbo flange to a place that bolts to the head. Really not necessary, though.

Lastly, 10.9 bolts are way overkill. 8.8 bolts would do just fine and even that's stronger than necessary.
