You can see apicture of that engine at L.Collari's web site:
And yes, they are Sirio made engines with gold heads and internal modifications done by Lauro's father Mauro Collari, and I understand that in the late ones, even the crankcase is done with LC logos and some differences than regular Sirio's.
There is another thread in this Forum about Innotech Collari engines with some great pictures of the new engines. You'll have to surf a bit to find it.
The engines shown at ACE are only the Off-Road engines, haven't seen the On-Road engines.
