Apollo - Aren't you forgetting that while the friction on each cam might be lower in a DOHC, there are twice as many cams, returning the overall effort requried to move the valves to the original value in a SOHC engine?

Not really.

A DOHC typically has less moving parts than a SOHC (no rockers/fingers). Less than half the workload of a sohc is thrust upon each dohc per intake and exhaust phase of the 4stroke cycle.

I think I know what you are getting at though, but I've currently hit my limit on explainations.
