After reading the "To rebuild or not to rebuild, that is the question... " post and seeing the images of the clogged water passages in the head, I decided a cooling system flush was in order. I used the Prestone 3 to 6 hour cleaner. I have seen cleaner pond water than the water that I drained out of that engine. Yikes! A completely worthwile thing to do to your 20 plus year old Monty.
