This is not an expert opinion.
I believe these gaskets allow the "right" amount of heat to be transferred
from the exhaust manifold to the intake manifold to help preheat the fuel
charge. Using washers instead of the gasket might disrupt this heat flow.
That is my guess.

Subject: Inlet/exhaust manifold joint

Fitting the inlet and exhaust manifolds to my BJ8 engine to-day I 
noticed a gap of about 110 thou between the underside of the inlet- and 
the top of the exhaust manifolds. The service parts list shows two 
joints to be used there (AEC950) but I'm at a loss as to what the 
purpose of these joints should be. If it's to keep the manifolds apart a 
couple of simple washers of the right thickness would do the job, or am 
I missing something?. Someone has an explanation?
