They are the same according to the parts fiche.

Yes and no.  You can swap them and they will fit, but different years have a different degree of advance.   Compared side by side you can see later years advance differently than early years.

In a pinch. Would this set up work? Able to tune. I really need to know if any k's will work in an f2 motor. Hondaman says he doesn't know bout the f's. thanks

AS mentioned, they carry the same parts number, even the last 3 digits are the same. The last 3 are the ones the denote minor changes to the basic part. So, I'd say they are completely interchangeable, if not identical.
