I believe they will swap around without too much issue.

That's what I am thinking. According to MarineEngine.com the crankcase gasket is the same part number so it makes me believe that it would work. Hate to buy a powerhead and not be able to use it. I know that at some point in the late 70s / earlier 80s they change the exhaust set-up and so I have to be careful about what year I use.
