Just make sure when you put the heatsink on you do not go down at an angle, you can chip the core. I have a Volcano 2 for my t-bird, that sucker was difficult to get on, but they generally put a notch in the clip so you can use a screwdriver to assist. Just make sure you put the heatsink on correctly and that you have it facing the correct direction. And try to get it right the first time, because if you remove the heatsink repeatedly you only increase the probability of damaging the cpu
