Are these air injection manifold broken?

[mw67rs]

I am replacing the engine in a 77 K10 with a new crate engine. I am planning to use the stock air injection manifolds. When I removed the manifolds I noticed that 3 of the 4 injection tube inside the manifold rattle around and 1 on each side is secure and will not move. They do not fall out but just move a little bit. I know nothing about air injection manifolds. Do these tubes are will move a little indicate that they are broken and I need to replace the manifolds? I just don't want to have trouble smogging this think in CA. Thanks for any help.
