My head gasket set has two exactly the same intake manifold gaskets. I wonder why. 
Otto …
I think that’s because they assume we’ll screw one up before we get it right 
Just kidding of course. Do they look like this …
The black one in the middle is the old gasket which was much thicker. I sent this picture to my friend who owns a british car repair shop and he said use either one (but not the old one !) and the trick is to lightly coat both sides with a sealant. Honestly I forget which one I did actually use but I sprayed both sides with copper gasket sealant. I’m sure a light coat of Permatex Ultra black would also work. Make sure you use a torque wrench to tighten to specs.
Dennis,
The two intake manifold gaskets in my head gasket set are dark grey. I have read that some cars have a spacer between the manifold and the head. So, probably the set has two gaskets for such cars: one gasket is used between the spacer and the head and the other is used between the spacer and the manifold.
Thanks for your tip concerning coating the gasket with sealant. I will use a light coat of Permatex Ultra Black.
By the way, I drove 400 kilometers (250 miles) on a highway last weekend and there were no coolant leaks. So, the water rail gaskets work.
I have removed everything else except the cruise control wire. How it should be removed?
I found the way to remove the cruise control cable. Now I am struggling with the wiper motor unit, because there is not enough room for the fuel rail to pass the unit when pulling the inlet manifold out.
There is a 5 mm thick bakelite (or similar material) block between the manifold and the head. The surface of this block is orange. I guess the block should not be removed. Instead, probably the new manifold gasket should be installed to this orange surface.
