Hey guys somebody posted a question the other day about an Australian z,1981 z 500.
Anyway his is missing the valves from when he bought it and was wondering if kz550 valves would be the same.
I was also wondering if he couldnt just use a complete head from a kz550 to possibly save some time and money.
Thanks

Yes. Head is the same.
Only main difference between the 500 and 550 is the stroke.

Thank you sir,you might have seen it over on kzr also.
