BIG iron and put the heat-sink in your oven at 300F for 20 minutes before you try. Take the heat sink out of the oven with mitts and be VERY careful with it.. It's hot..

You should have much better luck soldering to it if it's already near the melting point of solder and you only have to help get the local area over the edge.
