Engine IAC question - normally open or closed with no power?

Are 5.0 IAC valves normally open or closed? I just got a new Motor craft one from Rock Auto. Air blows through both holes without power. I've not checked one before, but I figured they were normally closed.
This one is for the shelf while they are available, and I want to make sure it is right while the return window is open.
Thanks!

Thanks.
