Default 81 Vacuum Problem

I recently changed motors to one with a 480 Speed Pro Cam and as a result I have very little vacuum. I am putting a 12v vacuum booster on the power brakes and was wondering if I can tee off of that and use it to also boost the rest of the vacuum system. The lights do work but it takes around 20 sec for the drivers headlight to open and then another 10 to 15 sec for the passenger side to open and about the same to close. It also seems that the climate control doesn't want to switch off of the floor setting.

You have leaks in your system,engines with as little as 10" vacuum will operate the system perfectly.
With my vacuum pump set at 6" I can make a tight system function very well.
