Interesting thought to somehow get the oil out of this "dead" area of the head...hmm... In my mopar experience, there's always excess oil in the rear of the passenger side head, and that oil is close to the baffle hole on most valve covers (ironically) It'd take a mind smarter than mine to re-cast heads with less of a pooling surface back there, or a better designed drain hole back into the valley. The oil up there isn't an insane amount...but it is enough to huff out the breather in the transition from zero, to 7000 rpm, back to zero, in a race engine with very little vacuum. If i'm understanding you correctly anyways.
