SOLVED! 318 2500-3000 rpm idling issue. Don't think its a regular vacuum leak. Swapped 2 intakes, 2 carbs ,and 6 different gaskets still no luck.

I'm going to other direction. There has so been so much bad advice from people whom have clearly never wrenched for a living or whom have product to sell I'm disinclined to participate further.
