I have only fiddled with 01-03 heads. I think those casting are identical in between the year models. As I think I mentioned in a mail to you, when we tried to enlarge the recesses for the intake valve seats, after 0,5mm we could see into the water jacket on 90 degrees of the circumference... That head had propably suffered from a core being out of place in the casting process! But other heads also seem to have little material in that region.

one question - as I understood it, the Cannondale engine lives or lived on as a 450 - which make? I couldn't quite make out or recognize it from the video (first or second video I think)
You are welcome, Tourist! Glad to hear you found some interesting stuff in them!
The engine was originally designed by Folan (Lars Nilsson) on order from Cannondale. I'm not sure about exactly how Folan was ripped off in the process, but there was no deal with Cannondale, nor production. Then the drawings turned up at Highland, and they produced a couple of 450īs until their owner was killed in an airplane crash in the US. After that Highland was scattered.
