Pilotmech, I think the straight finned heads are typically a 5 bolt pattern. The radials sport six cylinder studs. If they are of the same cylinder stud count, they typically will bolt on. Keep in mind two differences. The enduro head runs lower compression and mostly have a single plug. I took some of those like for like radial heads and milled them to raise the compression back. As I was planning on using a single plug ignition hey were  all fine. I also porcupined them similar to the Falta look.

Thanks Joe. Are there 250 mx radial heads? 5 bolt?
