A longer bolt is required for the balancer and it is a torque-to-yield bolt. We suggest using silicone and be sure to let it dry! We failed on the drying part as we rushed to get it done and make our way to a track rental. It caused a slight oil leak that had to be fixed before we left, thus causing us to be a little late. The second time around we used an ARP bolt, which Burcham torqued to 90 ft-lb. It pays to do it right the first time and not rush!
