massive reconfiguration time again.

well the kid on the techline said pretty much starting from the ground up and from the primary circuit on back.. it's all making sense that's for sure.. I have a lot of different direction to go of course with even another change and step up Springs but I wouldn't be surprised if it wasn't just tightening that secondary door even more. That's one thing the Edelbrock didn't have... well I guess they did some kind of weighted door...

yes, the Demon is and the Eddy Thunder series are copying the TQ air door, which was very successful if tuned properly. Also, check at some point check and see if you have any adjustment on how far that air door comes open, that's key as well. I think the Demon carbs will work great once tuned.
