Not much to add here. Hard to imagine this is going to come from me, but don't wory so much about the instruments and measurements. Just spend the time fiddling until it starts running good. See what I posted on the 18th - pretty similar to what Crackedback wrote. Open up the throttles for more rpm. As it warms up and you start to tune it in, you can lower it.

The engine is cold. Either hold the throttle open on the fast idle step, or just screw the idle stop in until its warm. Stock '69 440 fast idle speed was 1700 rpm! I'm too lazy to pull my '67 book off the shelf, but I'm sure even pre-smog, it was at least 1400 rpm. After a minute or two you can reduce it 3 or 400 rpm to something around 1000. Then when its warmer, a little less. Once your closer 800-900, then fiddle with idle mix and see what does.

7 mm hole is out line. Half that diameter - which is roughly 1/4 of the area is all that a PCV valve would be. So it doesn't seem like you have a vacuum leak at all.
