Other than the carb intakes? Also are the cams interchangable? For A GS550.

Returning Visitors
If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.
If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

The alpha sports parts look up suggests that they are the same. You should verify every part though.
12711-47000 is the 1978 Intake Shaft
12721-47000 is the 1978 Exhaust Shaft
The intake shaft has the same part no. for 1978 and 1980. But the exhaust shaft does not. Didn't check the sprockets, but you need to do that too. They may have different tooth counts across model years.

The cams do swap over. There is a difference between the years. My memory must be failing as I thought inlet and exhausts were different but from Mistercinder's post I guess it's just the latter. Anyway, they are interchangeable as I've swapped loads around over the years to the point of losing track which was which.
