From what I understand, a smaller bore
requires more valves in order to get the same airflow:displacement ratio as a larger bore engine with single intake and exhaust valves.
Edit: This may not be true, depending on the valve curtain size.
When it comes to the dohc and cam chain, I can't help but wonder if that added rotational mass actually eats some horsepower vs a pushrod engine.
Now, the added benefit of being able to adjust cam phase independently from intake/exhaust may make up for all of that, and provide better hp with more controllable emissions. I mean, there's a reason companies like AMG are putting 4-valve, DOHC large-displacement V8s in their vehicles, and I don't think it's just to increase the redline.
