Hello,
I rebuilt the MC2150 carb on my 79 F350 the kit only came with 2 base gaskets and a heat isolator plastic plate.
Im confused if im supposed to use the paper thin gasket under the egr plate and only on one side of the isolator or on both sides of the isolator?

K, thanks, I'll check it for flatness but I think it's ok. As I said, looks to be in perfect condition. Truck only has 46,000 miles on it. There is some evidence of carbon staining on the outside of the plate on the exhaust passage side so I'm suspecting the gasket may have been not so good on that side causing a vacuum leak. Can I still get these gaskets from the dealer?

FoMoCo 'service part replacement' plates were cast iron. There are two different types of EGR valves, two different types of mounting gaskets.

I called the dealer today and they said the spacer plate to intake gasket was obsolete. I then went to the parts place and bought a standard motor products gasket kit. When I looked at it the spacer plate to manifold gasket is paper. The only one listed on Rock auto is the one I bought local.
Any idea who makes a proper replacement gasket? I thought they were made out of a silver thicker metalized gasket material.

You're right on the material, and you definitely do not want to use the paper-thin gasket. It will burn out in quick order.
When I look up a '79 400 (are we talking about the same engine?) on Rock Auto, I see Fel-Pro 60332, but it definitely looks like paper.
That's pretty surprising. I can't tell if it really is paper or just a bad picture. You might call them and ask. If not, Napa or Carquest tend to be better about hard-to-find-right parts. If nothing comes out of that, you might take the risk and see how the Fel-Pro paper-looking gasket seals up; worst case you can make one out of header gasket material.
