Default Cooling Head for a Ninja MR21 B01

I have a Ninja MR21 B01 (GRP Version) that I have had since they first came out, just put new bearings, rod, etc... in it because I really like this motor. But after 2+ years the cooling head has taken quite a beating (Bent, Cracked). Everyone seems to be out of stock of the OEM version head, do any aftermarket cooling heads for different brand motors fit on it?

Thanks
Kyle

nova racing products make an after market head for it - it is designed to run cooler than the standard head (bewteen 20-30 deg F).

I'm not sure but have you looked into the orange GRP heads? the ones the come with the new GRP engines, which from what i've heard, it's pretty much the same as the GRP Ninja.
