Barman drags his masterpiece out....

 

"here's one we prepared earlier"

 

with the lift the cam part provides, it's going to be a big model!

There are plenty of working twin cam per head models about. Example:

Yeah, I know that engine and it's awesome. But, I was hoping that someone can make it much bigger. A fully working scaled model.

Anyone dares to try it?

That's is something that I had in mine. OK then... so it has been built already. Never mind. Forget about this challenge.

A model of a "functioning" engine block and corresponding gearbox was on my MOC to do list for years and I have made a couple of mock-ups and rough models.  There were a couple of problems I couldn't find a good solution for: The size of the cylinders and modeling the combustion chambers using Technic bricks, using standard springs for closing the valves, keeping friction low enough, etc. In the end, I abandoned the project and opted for a 3D-printed model (not my design): 

Which can be found on Thingiverse.
