Great to be back with you, Mark.
"Gemelocttivo" ? Twin Eight? Wouldn't that be "Gemelotto?" or maybe "Gemelododici" - Twin Twelve. Not being critical, and not an Italian scholar, just curious. Maybe it isn't even Italian. Latvian maybe?
Thanks
Gemello Cattivo or Evil Twin. It was a name I came up with the 308 V12 project some years back thinking I was trying to keep it looking pretty stock to the untrained eye away

I do have a technical question, though. Your project and excellent documentation finally gave me the courage to tackle the heads on my 308 2v. I understand you are going to put the heads on with the cams installed and locked at TDC (presumably the same for the bottom end). Is there an engineering reason to install the heads with the cams installed? or can it be done without the cams, and install them later? I'm trying to decide which method is better right now.

I don't think there is a huge reason to do them 1 way or the other. I like the cams in so the shims and buckets stay put and exactly the way I set them but it means the head has to be handled more carefully becasue some of the valves are open and that means easy to damage. Pick your poison.

BTW, I found two cracked thimbals (valve shim buckets) during head disassembly. I'm not familiar with the motorcycle shim-under-cap arrangement you are using. Does it use thimbals like the 308?
Yes the motorcycle setup has buckets too. The only difference is ferrari puts the shims on top of the bucket to make valve adjustments easier, the sport bikes put the shims under the bucket to save weight and retain the shims better...at the cost of requiring the cams to be removed to do a valve adjustment. Again its a pick your poison game but with the cams I chose shim under is the only option.
