I use Permatex Aviation form a gasket where the gasket meets the manifold and turbo housing. It is gas resistant also but will allow removal much easier then Motoseal.
Most of these flange gaskets get ripped in the middle upon removal from the manifold when they stick to it. I use a thin feeler gauge to push in to the gap between the gasket and manifold to pull off the turbo.
These foot flange gaskets really need to be reproduced.
