Thermoquad "super quad" questions!

So I recently picked up a Thermoquad #9800s on eBay for like 30 bucks and plan to put it on a mild 318 that's in my 70 Dart. I've torn it down cleaned it and rebuilt it but have some questions before I'm ready to bolt it on. First, I gather that the 9800s is a late run "super quad" or something to that effect that is based off of the 75 and later TQ carbs. Does this mean I need to make some modifications to get the best performance on my non smogger application? Also, as you can see, Mine is missing any choke attachments. Are they absolutely necessary? I live in a warm climate. One more question. Us the bowl vent tube meant to be plumbed to the valve cover breather? Thanks for any and all help.
