I think if you run an exhaust manifold leak for too long, you run the risk of warping the mating surfaces enough that if you do change it out someday, you will need to get the surface machined flat again.
How easily this will happen, i'm not really sure. I'm sure there is someone on this board with more experience than me on the subject!
