RZ350 Head

[2steve]

Is this head impractical for the street because it requires special fuel?
Just looking ahead on things and wondering.

yes, its impractical for street use. you could raise the cyls with an extra base gasket but then porting changes. better off using a cool head w replaceable domes. 20-22cc is the lowest id go
