You don't mention two things in your description:

1. Engine size... If I were to assume that your 69 block is a 302, I would say that despite your upgrades... you are over carbing. The 700 should be the max that you run on that thing. If you can borrow a 650 or 600cfm from someone, I'd suggest even trying that for a spin to see what you get. You might be surprised.

2. Exhaust size... You mention your headers' size, but not your exhaust... I personally like the bottom end power you get with a 2 1/4" dual setup, of course with an "H" pipe. But 2 1/2" should definetly be your max.
