Alright, I just got done doing these for the first time, and I will have to say, rotate the engine. Those wires boots extremely tight, and you need as much leverage as you can get. For the front three, use either gloved hands or locking pliers to get at them. For the back three, definitely rotate the engine, it isn't hard. All you have to do is put the car in neutral, unbolt the dogbones, and use a ratcheting strap. For the strap, attach the two hooks to the chassis right in front of the radiator, and to the engine brackets at the rear of the engine. Once you pull the strap tight, you will have easier access to the rear plugs. Once again, use gloved hands or locking pliers, shout some bad words, and voila, the plugs are available. For the #6 plug, you will probably need a ratchet joint or else you will have to remove the 02 sensor. All in all, not too bad. Would definitely recommend replacing the wires with some MSD's like I did, will make future work a heckuva lot easier.
