There are heat resistant sealants available for use on wood burning stoves and chimneys. I bought some from a general hardware store for the exhaust manifold on the 4-pushrod Salmson engine in my GN. These engines have no space for a normal exhaust manifold gasket and normally use a sort of copper washer, but the sealant in addition does a very good job... might be worth a try???
