You don't need to hold anything if you use an impat gun. Just be SUPER carefull when re-align the pulley onto the key way. If the alignment is off, your key way will get damage and the pulley will work it way loose. If this happen, you might need a new/rebuild engine. The other way, bottom of the tranny (newer model might be top), there should be 1 or 2 plastic cover. Remove the cover and use something to lock up the tranny.

Guys, I have a question on pulleys....
I have been told that upgrading the crank pulley on a naturally aspirated engine is pointless as it will not offer any gains.
Can anyone shed some light on whether this is true?

rotational mass when reduced always produces more power...

In reality, it does not produces more power but use less power to spin in return give back the hp. I think M-benz has this mods but couldn't felt a thing. He then removed and sold it. The concern with these type of mod is that, now the weight is offset and might cause more vibration but the damper will control that and you won't feel it but it is there. Just think about this, when you removed the weight from one end of the engine, you will offset the weight balance of the crank shaft from the way the factory designed and balanced it.

You also raise another good point but I think that the dampening effect is what the real issue is, not the weight per say. Stock dampners are heavy and have a vibration absorbing material, like rubber, these AMS pulleys are quite a bit lighter but they do feature an integrated dampner. I ran a fluid dampner on a 327 years ago and never had any issues with it and it was a whole lot lighter than the stock one was as well. It has more to do with the virbation absorbtion/cancellation than weight IMO as a rotating balanced assembly is just that, balanced while rotating, not in a 'shelf-state' where differences in weight from one end to the other would play a significant role. Example being a wheel, a high offset wheel has a whole lot more weight distributed on the out facing side than the inner side, it does not effect the overall balance while rotating, it is also a a balanced rotating assembly.
I made mention on another thread that an absolute killer product would be a reduced mass crank pulley with an integral fluid dampner and under-drive pulley sey combination, it wouldn't be cheap but it would be a great product for those chasing to shave 1/10th's off in the quarter.
I also have an AMS pulley, maybe I'll play around with it and try to come up with a very simple test that I can then apply to the stock pulley as well. I think I have an idea...

Good example but the high offset of the wheel is already countered with weight added thickness of the design in the wheel. If you look at the inside of the rim with high offset, there's is an extra ring/ridges near the outer side of the rim to countered the extra weight of the high offset weight added on the inner side of the rim.
