Cylinder heads?

Google image search FTW.
One exhaust and one inlet valve per cylinder are driven by each cam, the opposing cam drives the other pair.

Yes I'm aware their 4 cylinders, interest is only in the heads.
I meant in the same way altering the cam on a single cam alters both intake and exhaust compared to a common twin cam motor where one cam operate intake valves, the other being exhaust valves. I figure one cam in those motors have a intake and exhaust valve in one cylinder attached to it, so altering cam timing would alter both intake and exhaust timing on that side of the engine similar to a single cam motor.
It's nothing like a single cam head. When you actually look at the airflow, a 4-valve DOHC has more in common with a 2-valve SOHC head than the designs you posted did.It's nothing like a single cam head.
