Edelbrock Air Gap on Magnum 318 Problems

I went with the blue cam and kept working my way up squirter size until I settled on a .040 squirter with a hollow squirter screw.
It's running pretty good now. It's pretty well night and day to before. Before, it wouldn't take throttle quickly off idle. Now, it almost feels good. I have a little stumble below 1500 rpm. I could have went to a bigger squirter but decided to drive it some before going any farther.
The secondaries work great so I left everything stock in the rear.
If my car was automatic, I probably wouldn't have any stumble now.
