As expected

I was lucky: none of the bolts that attach the manifold to
the engine snapped! Only the four bolts that keep the two
manifolds together had snapped off. But by heating and
gently twisting them I could get them off.

As expected the manifold was broken in two !!
Probably because the valve that controls the hot air intake
collapsed. This provented cylinder 4,5,6 from releasing
their heat. Yesterday I ordered gaskets, they will be in on
tuesday. That gives me time to clean up some parts.
