Help! New Carburetor????!

Way cool you guys!!!!!!!!!!!!!!!
Do I use ported/timed vacume advance or manifold vac advance opening? The previous quadrajet rig set up, I checked when running and it had constant vac, but it was the wrong carb. What vac hole should I block off and what one to use for advance?
Johnny Dart, Where did you get your linkage & springs?
Anybody have sugestion on air cleaner set up? The 14" Edelbrock pro-flo #1221 would need $20.00 banjo fitting and hood clearance still looks close. Besides, you can't see my new carb with it on!
