The large idle air bleeds may be too large. I dial mine in using a AFR gauge.
Makes a big difference. The vacuum gauge should not hunt at idle. is the timing stable at idle?
Is one cylinder missing?

yup probabily a 106LSA cam.. They like lots of idle timing 24ish should be plenty.

What carb model? what are the pri and sec air bleeds sizes. what was stock orignionally?
Why did you change it?

The tuning on then idle air blleeds is critical very small changes make a big difference.
The AFR gauge makes it real easy.
