Not me. I ran a Weiand Action+ on my 410 with the divider fully in place, about a 1/2” removed, and then with it like you’ve shown. Somebody did that mod looking for a little more horsepower. Spend your time tuning the carburetor etc as you would regardless. I noticed no difference running around on the street, but saw small gains at the strip whittling away at the divider.
