Sorry to break the news but in my 35 years of experience putting used manifolds & risers on your on your engines would be the most expensive option when you have to rebuild an engine. (or just junk one with a cracked block) Years ago I put a set of elbows that had been used for a year up in my garage loft. I had boiled them clean first. A number years later I had to move the boxes. They made a funny noise. I opened the boxes & both elbows had crumbled to pieces.
I found out that once salt gets into cast iron, you can't get it out. That is why you can't convert a raw(salt) water cooled block to fresh water cooling.
