| * The included pamphlet with this kit suggests assembling per the FSM using the recommended gaskets from HD. If steel gaskets are used in place of the factory composite gaskets, look carefully at the position of the rivets. Any rivet that may get sandwiched between the head and cylinder will need to be removed. They're very easy to remove using a bench grinder or a Dremel tool with the metal cutting blade attached. Just grind away the entire tab that contains the rivet with the grinder or you can grind down just the rivet with the Dremil. Make sure to de-burr the ends if needed.

| * Lightly lube the threads, shanks, and undersides of the heads on the head bolts and install finger tight. Torque in the order shown in your FSM. For multi-layer steel gaskets (mls), torque all head bolts in five pulls starting at 9, 14, 22, 35, and final torque at 42 ft-lbs. For composition type gaskets, follow the procedure described in the FSM.
