Not really. You still need to have the valve stem protrude through the guide the full length of it's travel and additionally have room for the closing rocker under a collet midway down the stem. They might take even MORE depth than the standard BMW arrangement. I'm also curious how those cams are driven. I wonder if the cams, rockers, valves and shims are standard ducati parts.
