You are not going to try and fire until the results and pictures of static timing procedure; and you may be rotating some more with plugs out after.
But yes you will be using the jumper. That is later after static timing procedure is done. If it's out of time because of chain or valve train, you would not want to try and start. You can damage the motor. Be patient. You may have to take valve covers off at some point.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
