This could be an embarrassment but I'm going to ask anyway.

Why don't all engines use overhead camshafts? What is gained by the complexity of a camshaft/pushrod/rocker system? Surely OHC is simpler, cheaper, more efficient, more reliable etc...

Might have been asked a thousand times before, but there you go.

Thanks all, glad it wasn't a stupid question.
