The cure is better heads, 3.03 gears in diff. (if not already there).
If you want even better:
aluminum intake
carb spacer (for heat dissipation)
better cam
better lifters
2.02 heads
4 speed auto trans
3.03 gears in diff. (if not already there)

Rebuilt the Rochester 2GS a couple of yrs. ago. I hooked a vac. gauge to it, but, mostly tuned it by ear. I should go back through the carb. just to clean and make sure no junk and spend some time with the vac. gauge to dial it in better.
