Not an expert but here are a few thoughts.

What is the upper power range of those cams? The stock rods become questionable above about 6700rpm which is where the 3.2 cams start to fall off.

964's are about the most radical cams that seem to be smogable if that is relevant.

The stock 3.2 cam is a very good mid range power turbo cam. Usually a more aggressive cam is going to move the power band to a higher rpm at the expense of some TQ.

On the other side, if you are running stock higher compression pistons, a more aggressive cam lowers the effective compression ratio some. 964's lower it about a half point over your SC/3.2 cam.
