If you are making power and dump the clutch or hit it hard with an auto you absolutely need them. If you never hit it hard you don't. I was racing my '65 with a 4 speed and got wheel hop so bad it grenaded my 10-bolt and dropped the driveshaft with the pinion gear still attached.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
