I found highway driving sucks oil into headers. That is 3400 rpm steady for a half an hour. I do not have baffles in my valve covers and they are the old M/T kind so they are short. If you have a taller set and can plumb from the front face of the valve cover with a baffle I can't see any issues.
Otherwise street driving and at the track I have no issues.
