Default Throttle Body Modifications??

I bought a stock '02 Vette DBW throttle body to put on my LS6 but the cable drive TB was opened up so the intake is wider. The picture shows the TB intake bell was widened so it goes all the way to the outer edge but the butterflies in both are still the 75mm opening.

I can do this to the DBW TB, but is it worth it? Will I lose any HP by not opening up the intake bell??
