I think there an excellent street head in a normal car, really good for hot rods as well. While there ultimate cfm flow isn’t super high, they can be a very good head.
IIRC,
@mderoy340 runs them on his car.
Again, IIRC, I think he ran a PB in the 11’s? I’m not sure, perhaps he will choke in. His combo is not set on kill FWIW.
It’s a dead reliable set up.
I don’t remember anybody trying a “On Kill” with these heads. But I don’t see a reason they would not perform really well.
