I have heard that the "O" was a locating mark for the assemblers - that those marks are supposed be on the intake side when installed; if you look closely the covers are longer / taller on one side for rocker arm clearance and we've all seen the marks made on the inside when they're installed backwards, and likely heard the difference too. Cheers.
