Are gaskets required on both side of manifold to head insulator?
 
The Andover drawing shows no gaskets (1 & 1A are 1/16" & 1'8" thick respectively):

I use a paper gasket on either side of the phenolic spacer along with Yamabond. Phenolic is not a gasket. If you apply yamabond on the phenolic and the head the intake will suck all the gasket goo and there will be an air leak. That makes an airtight seal. for the carb to manifold I rely on the o-ring.
 
That might depend on the insulator surface.
I got a Bakelite insulator off M,M and I Engineering which got a light coat of WellSeal to all four surfaces and left to tack off.

Heat might still soak through to the manifolds via the fasteners at rest with a hot engine.
