They (2ea.)are in the intake. The intake manifold will need to be removed to get to them. The wire harness and intake manifold gasket should both be replaced when reassembling.
No, You don't put anything on Head, Exahust or intake gaskets. CJ actually you do put a 1/8'th inch bead of black silicone on the gasket to ensure no leaks occur and it also helps hold the gasket in place when your putting the intake manifold on. I'm a ford master technician, you ALWAYS use silicone when replacing intake and head gaskets. =DK
Yes they do at the intake manifold gaskets.
It should be printed on your intake manifold.
what about it?
Remove the intake manifold retaining bolts from your 1996 Chevy Astro Van. Remove the manifold gasket and clean the surface. Reverse the process to install the new intake manifold gasket.
There is no difference,,,
yes
Assuming this is a 4.3L engine, the upper intake manifold gasket would be between the upper intake manifold and the lower intake manifold.

Yes.
The 350 cubic inch Chevrolet intake manifold bolts have a torque specification of Haiti pounds psi. The bolts should be torqued at 40 pound intervals.
