    As long as you want to stay NA, then they are worth it. I would only recomend a set that includes a new SFI approved balancer.

    The SFI style replaces the balancer. The cheaper style uses a long bolt and sandwiches the new pulley between the stock balancer and the block. People have had problems with their balancers actually falling off, even as far as crank failure from vibrations. Pesonally, I just dont like the idea of my balancer hanging out in space on a Taiwan made bolt.
