For breaking it loose I've always used one of the power steering brackets. Use one of the crank pulley bolt holes and one of the water pump bolt holes. Should work for tightening down as well. Generally what I do is crank it down as tight as I can until the motor starts turning then spin the motor around a least once. Fully assembled engine in car with the spark plugs in. Centrifugal force will do the rest after ya fire it up.
