Any product recommendations for high temp sealant/ retort cement for resealing a dry firebox to a cast iron heat exchanger and resealing the exchanger to the draft hood?
Something that can be applied outside the joints as the boiler won't be coming apart to put the sealant under the flanges.

RTV sillycone is good up to 450° If you are sealing an oil furnace vent that may not be a high enough rating. I have had good success with High Temperature Stove gasket cement. its black and it comes in a caulk gun tube. Rated to 2000°F

After you make that expensive repair and you still have the same problem, What will you check next?
