[No Groc Getter]

Did anyone say good head bolts or studs and a good torque wrench. After you fire it up and bring it to operating temperature, pull off the upper and pull the valve covers and retorque them again. Hit the intake again too. It will suprise you how much torque the intake loses. With plenty of antiseize on the threads make slow even pulls on the wrench using only the far end of the handle. Happy wrenching and don't forget the gloves or you'll have busted knucks.
