Tuning for Mild Cam, Headers, etc....

That looks pretty good! After I come up and stop it still stays at about 1200rpm and no way to get it back down unless I shut it off and start it back. I tried adjusting the screw again to get my IAC lower but it seems to not want to go under 39 steps.

That's funny, I had the same problem with my '7427 in the camaro.....start up, idles good, put in gear and back to P/N and IAC/idle won't come back down, i think mine wouldn't go below 27 steps. I ended up switching to a Big Block bin to start, and all that went away, along with having a better spark map for my application.

A lot of times that is do to "IAC - Position vs Temp" I cut them in half is usually enough.
