I think this brings us back to excessive blow by, even *with* a functional PCV system.

Looking under carb there is no reason why it should go only to one. It looks evenly coated both ways on the bottom of the carb, but it is there so at least some of that sludge is coming from the PCV. What is causing that and is it just because it sat without driving for a long time?

Yes, could very well be ...
That is why I suggest leaving the PCV unhooked at first. to eliminate that possible source.
However, if you really do have blow by that bad, that's an issue ... But IMO an issue to delve into later.

I *think* you're seeing some staining from the PCV and a larger amount of oil leak from one or two ports being shared by the other cylinders on that side of the plenum.
I didn't remove the intake or have a firsthand opportunity to examine any of the sealing surfaces.
That some areas of the intake gaskets pulled away cleanly from the heads is somewhat telling.

I did. It had the correct sequence on the instructions (which I actually read! I do not read instructions often and when I do I get leaks so I may want to stay away from that like usual) that came with the manifold.

The sludge
hharris8 my best guess would be just as you said the pvc but more then likely it came from the time when it was running and could be from weak rings or bad valve guide seals.The pvc does suck vacume from the valve cover,s and would leave a deposit of greasy gook after a while how many miles were on the engine.You know hharris8 just take some carb cleaner spray and let both sides have it and bet most of that sludge will be gone or less noticeable.

I hope I'm not coming off as critical.
And I certainly don't doubt your ability to read or follow simple directions.
Just trying to get a better understanding of how and why this has happened to you.

The Automotive Leak Detector
That's ok It was just a hobby for me I had a vacume leak in the evap system and took months to track it down the dealer wanted like $400.00 and they were going to pull the tank after I found a broken vent valve and I told them to forget it then I built the leak detector to help find my problem and it turned out to be a pin hole in the line from the charcole canister to the vent valve after putting in dye because smoke wasn't showing up any were it took like five minutes to locate the pin hole and I do mean pin as in so tiny that you couldn't see smoke coming out of the hole and you couldn't see it with your eye until dye was added to the oil and then it dyed the location of the leak.And it was only visible under ultraviolet light.
