Intake Fitment

You are all over the map, and I’m not even sure what you want to fix.

That cam, in gear, will probably idle at 11 - 12 in.hg.

If you have cold start running issues, it’s in the choke system and adjustments.

If it does not come off the fast idle setting, the rpm’s will continue to go up as it warms up

Spraying stuff around the intake is not a great way to determine if you have a vacuum leak.

Vacuum readings during cold start up will not provide any meaningful info.

Maybe share what color the smoke is. November in Pittsburgh, all cars smoke when they start.

If your plugs are reasonably clean, your problem is likely not that bad.

After it’s all warmed up, is the 10-11”hg your only issue? Add initial timing.
