The problem lies not with your waterblock, but the amount of pressure applied by your waterblock. I have a ti4600 watercooled as well. The fact became that when I applied the proper amount of force to the block, the PCB would flex, and the core would no longer be flat against the base of the waterblock.
So here's what I did. I took a spring clip from and old 486, and stuck a thick layer of neoprene to the back of the card, and then drilled two holes into the clip matching up to the holes for mounting the block. Then, just mount the clip on the back, so you can control the flex of the card.

The really funny thing is that I spoke over email SEVERAL times with DangerDen on this EXACT problem, yet they paid no heed.

You can see a prototype of what I'm talking about:

I used two paperclips and twisted them together and into the shape of a spring clip. Worked fairly well too. Just make sure that they don't come to a point behind the core...
