Timing curves for MSD Digital E-Curve Distributor?

When I tried to set the secondary throttle plates I found the butterfly’s were uneven.
If I had one exposing enough transition slot the other would be covered! I think that might be one issue?
I ordered the 650 card 1906 because I want the drive ability for this 360 in the fastback .

I am also building a 69 340 4sp Swinger that has a 408 W2 solid roller motor with a Pro Systems custom double pumper and a Daytona Sensors digital ignition.
