Can anyone tell me if adding a set of performance underdrive pulleys like the ones made by March to my 66 396/325hp would be a good idea?

Hi
I put the march 6090's (3 belt) on my s.b. and really like the results. Here in the low desert it ran real good and stayed cool. Bought a second set for the new engine that is almost ready to drop in
