Since the PCV valve had so much grime, but the valley has very little sludge (besides the edges having a thin coat of black, there is none) could that SeaFoam I put in it and ran in it cleaned the pistons and put that into the PCV? Just a thought.

This would be another case where, if everything was operating properly, any residue displaced by the voodoo additive would be distributed throughout the engine and would show up on both sides. It showing up on one side only is the issue.
The intake stream contains vacuum, leading from the top of the opening (carburetor) to the valves in the heads. It is conceivably possible the intake valves on that side are leaking badly, and each compression stroke pushes stuff up and out of the combustion chamber and into the intake manifold. But the engine would run like crap so I don't think that's your problem.
In my mind, this involves the PCV system and/or the EGR supply channel (that delivers a small amount of exhaust gases back into the combustion chambers) on that one side.
But that seems like a lot of unburnt oil - which strongly points at the PCV system - and not carbon - which would indicate exhaust. You say your PCV valve was grimy, that could be another indicator and even a cause (although one side only has me curious, and I'd wonder what the underside of the carburetor looks like).
In any event, I would clean and possibly replace the PCV valve at a minimum.

Chris, this is a *non-EGR* aftermarket aluminum manifold from what I read when looking at Edelbrock's instructions.
Thankfully it's a LOT lighter than the stock CI manifold while trying to place it squarely on the sealant.
The oil has to be coming from somewhere, and I don't think the PCV is going to dump into only one side like that either.
Intakes can leak internally (to the lifter valley) and oil mist will move around towards other cylinders on that plenum.
ATF coming in through a vacuum line will also cause a smoke screen, and that would be isolated to whatever side the vacuum port was on.
I used to say that diagnosis over the Internet was akin to brain surgery over the telephone.
Evidently they are doing that now...

I agree ...
It is my suspicion that when the valve covers were off they got turned upside down and the PCV and line got filled with grimy oil, when it got started it sucked it in and just hasn't been run long enough to suck it all out.
That oil in the intake is pretty grimy, to grimy to be coming from anywhere but the PCV.
Clean it all up, replace the PCV if needed ... As I've said a couple of times. I would leave it unhooked at first just to see if the smoke clears up.
I also wonder about one plane and not the other, that has me curious!
Sure would like to see the bottom of the carb. from the rear forward and not real close, just back enough to see the WHOLE carb. hint hint hint ...

I have seen this happen on AMC v8's and can see it happening with the Ford's too.
Is there anything going to that port like auto vac line? The PCV should go to the base of the carb so the vapors go evenly to all cly's.
Yes replace the PCV and run the motor a lot more. I have seen the inside of exh get coated and take a long time to burn out and stop smoking.
Bad head gaskets filling the muffler with anti freeze. After fixed the motor still smoked! Took a long time and lot of driving on the high way for it to clear up.

I cleaned with steel wool and brake cleaner and gasket remover. I guess what is left is some Gaskacinch or something. I cannot seem to get it off without scratching it.
Now here is a good point I just thought of... alluding to Fuzzy's point of where the PCV valve is hooked up.
One of the mechanics several years ago was explaining to me that not all manifold vacuum is the same, although I forget the entire explanation... but there are different manifold vacuum sources for very particular reasons... and this I imagine could be a big deal in a dual-plane manifold.
As for these larger-diameter sources, one is for the PCV valve and the other typically for the power brake booster (and is sometimes tee'd off to other devices).
Point being, be absolutely certain you have things connected as they're designed to operate; I know absolutely nothing about that carburetor or manifold.

I have the PCV in the correct location. The brake booster is attached to the vacuum tree, but Edelbrock said that was OK.
Now I put Gaskacing on the head, lay the gasket, apply RTV around water ports and a tall and wide bead for end seals, install 4 screws of dropping manifold on, put on manifold, and torque down in proper sequence at proper torque correct? And do I tighten to full torque or do I wait?
I have never used gaskacinch but my understanding that stuff is just to keep the gaskets stuck in place while installing the manifold.
The instructions for some sealants give you very explicit instructions, you should read yours... what I generally do is initially install to the lower end of the torque range, then tighten stuff up a bit after 24 hours and THEN add coolant.
Just remember to not over-do it with the sealant around the water ports, just a thin layer smoothed out with your finger is all that's needed (I think that's what they told you to do, right?).
But for the end seals, ensure your bead is large enough to fill that gap; I build up the bead on the block and also apply a thin film on the mating side of the manifold so that RTV on one side sticks to RTV on the other side.
Installed and tightened bolts by putting my hand directly above the socket (not on the handle) and tightening. This way I am not tightening to 18lbs (or whatever the torque specs are). Tomorrow at this time I will torque completely down.
Oh, and you can see in the pic of the valley that it is not gunned up. I rubber my finger in the center and it turned my finger black like used oil, but it was not thick or sticky.
