Engine shakes BADLY!!

I'll go with the cam is installed properly. I wont doubt their work as you know them way better then I do.

Now my question is, when you're idling in gear, does the engine seem to be loading up like it's rich??? That idle vacuum you're pulling with a stock spec carb could be dumping fuel with only 5". Even the HP carbs come stock with a 6.5" Power valve at the lowest if I recall.
