Does it come with dust caps for the test ports?

Yes the Zurn Wilkins 350 has plastic screw in caps for the 4 test cocks. Note that the model 350 protects against backsiphonage and backpressure of polluted water, where a potential health hazard does not exist. In Idaho the Double Check Valve Assemblies are not allowed on irrigation systems anymore, so assemblies like this not rated "lead free" have very limited applications anymore.

Is this assembly lead free?

No, it is not. The lead free version is a 350XL

Spec on zurn site says 12.25" length. Amazon lists 17". What is 1" 350 length?

It’s closer to the 12.25. I think the box it comes in is likely 17”.

Why wont the valves close?

Might be tight at first try to work them in
