Well I suppose I can answer my own question now.
To watercool the EVGA 770 SC Dual Bios Edition (02G-P4-2776).
What you need:
Phillips Screw Driver
770 Backplate of some variety is recommended
Pliers (NeedleNose/Standard) or Vice Grips
VID-NX680 by Koolance (tested/approved)
and of course a watercooling loop.

The Process
Remove the air cooler
Clean the paste off
Set it aside

Notice the screw mounts on the VID-NX680
With th pliers, unscrew/remove the one you do not need (it only gets in the way and causes pressure contact on a chip, it will not leak from this point after you remove the screw)
You will know the one you do not need by it being the one on the end opposite the gpu and connections.

Now notice the contact points on the waterblock.
where you removed the screw is the only place optimal contact is not made, but we will somewhat correct this.
Start your thermal padding, all points but the long one where the screw was removed.
Take your Thermal padding material, put it over the removed screw mount, all the way against the contact point, but not on it. Cut it so that it fills the gap from contact point to the end of the block (a few milli thick). Trim i so it is the same width as the contact point. You should take the time to notice what you are doing here, you are creating a contact point filler from the contact point to the end of the block. The piece you just cut should be created atleast 2 more times and stacked. Just keep pulling the film off and sticking them on top of one another. Finally, cut your thermal padding to cover thiss final contact point as well as the filler we just made. This padding should cover the contact point from the end closes to the gpu to the end of the block. If done correctly you will realize that you have now made contact with the final 3 chip modules which originally were the only things keeping this from being a perfect fit.

Put your paste on your GPU, mount the block, screw the screws, flip the card, add the backplate, screw the screws.

You may notice that, depending on your backplate, you have some screws left over. Does it bother you? Doesn't bother me.

Take this information as what you will, this was my process for 2 cards, they work fine, no problems. This is MY experience, experiences may differ. Use extreme caution when working on an component and do so at YOUR OWN RISK.

NOTE: The VID-NX68 comes with plugs, thermal padding, and paste. as well as some screws for backplates and spacers. I used the plugs and padding it came with, the backplate from EVGA and the screws with it, I used some arctic silver I had around from a previous build.

Don't have a good pick of the block mounting, but this is what i got.
