Highest flowing sbm heads?

I beat multiple Hellcats at Tulsa Dragway at the Mopar event a few years ago with that little 415", now we obviously have quite a bit more....but that weekend I ran a 10.48 @ 126....to date I have never been beaten by any modern Challenger or Charger....it can happen as there are some that are highly modified and run very hard but that's why I said 98% of them would be getting gapped.
And 98% of them couldn't get the power to the ground. I have seen dozens of late model Challengers that just can't hook.
