Victor340 and RPM manifold testing

I have mentioned this before on here.
Buddy has a black 72 cuda chassis car.
Now is a high 4 sec Best machine big block car.
Used to have a small block stroker roller B1BA deal in it.
Ran 9.06-9.08 with it. Swapped the Victor for a super Victor to try to get it in the 8’s…. Ran mid- high 9 teens
That all said, I don’t remember now what level of work( if any ) was done to the two intakes
