My opinion - if it gets wets (water, oil, gas - whatever) then use it.

If it's a dry part - like shift covers, intake manifolds etc - don't bother.
 
Gasket compound?? If your talking about those glues, never!
Use silicone sparingly on good surhaces, a little more on rough or pitted surfaces.
 
I use aerosol HiTac (sp)sprayed lightly on head gaskets (both sides of gasket, on the block, on the head). This has worked very well for many years. I use a light coating of silicone on the valve cover to glue the gasket to the valve cover, setting the gasket side down on a very flat surface, place a weight on the valve cover and let it set for 24 hours or more, this makes installation of the valve cover a breeze. I do not apply anything to the other side of the valve cover gasket. This makes it easy to remove the valve cover and re-installing if anything needs attention after the first start up.
 
When I install gaskets I use enough stiff grease to hold in place and nothing else except head gaskets and I will use copper cote spray
 
I'm fairly sure that the factory used none. I agree with Larry and his approach, these are old machines and things (surfaces) deteriorate. Use any 'goop' sparingly. HTH
