Dont have it in front of me but I am 90% sure I pulled it from an 86. Here is a pic of an 87. The big question is can I run an 86 manifold on a 85. A close of pic of a complete 86-88 would be nice.
Post #11 is a '86 or later intake. That EGR # changes to a number that fits '86 and later but '85 is single year intake and one year EGR, '86 is single year then '87 & '88 are the same. If you have a parts catalog the information is there.
Thats is good to know, so I will buy an 86 EGR valve BUT the hole in question appears to be for a heat tube, Not to sure where it goes or if I need it. Or if I need the EGR at all. Maybe your 86 parts book shows where the tube goes.

Sorry, we should have been more clear. The tube from the passenger side exhaust manifold goes to that hole on the back/side your intake, which internally then goes to the EGR valve on the top/center, which will open and close under certain conditions to allow the exhaust gasses to be recycled into your intake air. So when we say that's an EGR port, we just mean that it's part of the same system. The tube you show in the pictures looks just like mine (as far as I can tell) so I have no reason to doubt that it'll bolt up. But you can delete that whole EGR system with a couple of block off plates. I'm about to do the same as my new headers do not have an EGR tube.
If you block them off, some people have reported seeing the check engine light come on from time to time, and others have said they haven't seen the check engine light come on at all.
There are ways to program it out of your ECU so that you don't get a check engine light, but I can't be much help with that part as I haven't done it before. You'd need a new PROM chip for that.
Does anyone make the block off plates, I dont really want to fab them and can you get the gasket for the heat tube to the manifold. I would think that only one port on the top of the intake goes to the intake so if I leave the EGR on it (closed) I dont have to worry about the side port, I could leave it open right.

To block the port that would typically go to the exhaust manifold I don't know why (if prepped correctly) you couldn't use a 'cup style' expansion plug.
So my intake is an 86, 14086069, but the interesting thing is the egr gets exhaust from the drivers side head port too. Passenger side gets it from the exhaust manifold tube. Wonder what would happen if i hooked up the egr using the one head port, no air injection, or cat. Could it hurt? I would still have to block the right side.
