Hi, I have either a 1990, or 1991 400rr that was imported to the United States. The guy i bought it from dropped a valve and tore the head all apart, its worthless. Can I use any year NC29 head, or just a 1990 or 1991?

Thanks for your help!

Hello and welcome.

As far as I am aware you can use any head from any year 29,
