Flat spot/bog in 1st gear, after shifting gears
2Low8s:
Pulled the mix screws and springs. Measured out to .089 with my #43, couldn't get a #42 in there.
Still ran fine screwed all the way in with no springs.

Yup try 33 - 35.
quadrajam:
Like 77 says, throttle down the idle tubes and try it.
I saw that you had removed the lead plugs in the main casting
that blocked the idle air bypass. Did you check that the rest of
the bypass passages were still functional? The right gasket holes?
on both sides? about maybe .050 inch holes???.
Might need more air...??
Pull off a small manifold vacuum hose or cap at hot normal idle and see what happens.
It might be a challenge getting a perfect idle with that much cam, rocker and
intake on a 305.
77cruiser:
You could make some of these if you want to make it easier to adjust.
2Low8s:
I got the Rona last week, so I'm taking advantage of the time to dig into the carb now that I'm feeling better and can function. I'll start out at .033 as well as resize my IDCR to .046. I'll walk it in to .035 if need be.
After looking more closely at my transfer slots I realized they aren't square and that's probably why I could turn the screws in all the way and not kill the motor.
I like your idea but those seem a bit overkill for me and above my fabrication skill set! I can glue metal together, but it's like me- Ugly but it works.
