I wounder if the larger valve heads 37mm vs 35mm would have
more material in those areas?

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.

That's a non-understanding stingy neighbour! 😉
My machinist has large saw, so when I want to "dismember" (!) somebo... something, I know the where to go!

Assembly with the old type piston/sleeve to test if the modifications to the cooling system (new coolers, connected in parallell with each other) will improve flow and capacity.
The new lifters and welded/ground cams with "running-in-grease".
Happy Easter everyone!  | |

Todays efforts resulted in a coolant expansion tank. I got me a magnifying glass to mount inside my welding helmet. So much easier to have some control over the welding pool!  | |

Thank you very much, but hold your horses, it is only a couple of alu-sheets welded together!  Maybe it can serve as a pocket bottle as well?

brilliant idea with the mag glass, i'll tell my half blind panel beater neighbor with the beef saw, perhaps he will be grateful enough to spare me some diced bullocks ribs
I agree husabelg the skill with that kind of creation is in creating a weld seam capable of retaining fluids, something i haven't always been able to achieve particularly with fuel containers
