Edelbrock 2.055 (30 degree back-cut) testing

Is there ever any gain to back cutting the exhaust valve? I've heard people say there is, but never seen any testing and I don't see how it could have any effect.

Weingartner talks about backcutting the intake in pretty much every video, he says there is no real improvement in doing it to the exhaust though
