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.

Only thing that's probably gonna limit me for the moment is the car is not driveable, still need to build the clutch pedals and the body work rewire all the dash electrical yada yada. So I can't test it under load right this minute gonna be a few months. I figure reading plugs is a bit tough idling in the driveway you need to be under load to get a good read on them I assume?
Correct way to read plugs. Make a WOT run into high gear, back off the gas and switch the key off. Coast to the side of the road and read the plugs. Otherwise, you're reading pulling into the driveway almost at idle.
