Sounds like you don't have an advance style timing light. You're after the total timing with the vacuum disconnected. I believe this car should like about 35° total which should be in around 3,500 rpm. You can get a timing tape for $5.99 here: Pontiac Timing Tape Once you install this, you will not run out of marks. If getting your total timing correct makes your timing at idle too high, you will need to get a recurve kit - a liklihood if it's the stock distributor.
The factory Q-jet is 750 cfm. The factory restricted the power by inserting a small clip on the passenger side linkage. It could be removed in less than a minute, hence most of them have already been removed. If you could mechanically open both sets of secondary air valves, I doubt that it could be installed on your car. Go easy on those spring adjustments, a little goes a very long way.
