EDIT: ^Yep, I wasn't one of the guys with a deformed one but mine didn't work for me anyway. I think mine was made of something different than the ones that were deforming, I think mine is sturdier than that. If only it had been cut right.

So-- I had to scrap that unfortunately. I was quite proud of how simply and securely I had it mounted too.
So instead, I bought some of this thin stick-on heatshield from Jegs comprised of a high temp adhesive, a layer of fiberglass, then aluminum foil. First I formed it tightly around the curves of the LIM -- making sure to shield all the way to the bottom edge. Then I added a second layer towards the top where I had more clearance and where the downpipe will run. The second layer I wrapped straigt & tight and left a bit of an air-gap instead of following the curves.
Its ugly now, but hopefully pretty functional. I also have one of these phenolic spacer gaskets that act as a barrier for conducted heat transfer from the block to the manifold. Not sure how well it will be as a gasket since its pretty hard and inflexible, but thats what RTV is for anyway. There definitely seems to be a lot of surface area on the LIM for heat conduction from the block that should now be blocked.

Your LIM wrapping job looks MUCH better than mine HAHA. I got the same kind of stuff to cover mine, I don't think I have pics on my computer though. It would just make you laugh anyway haha.
Also, I'd check that gasket first if I were you. Is it from Gizzmo or somewhere else? I got one from Gizzmo and it didn't match up exactly with the OEM gasket and ended up not completely covering the EGR port, which gave me an air leak. Before I figured that out I also tried red RTV, so that doesn't work either LOL. Just put the phenolic gasket on top of the OEM one and see if it's EXACTLY like the OEM one (you can see the difference of mine in the pics). I ended up getting some spacers made with waterjet that I'm going to use to space my fuel rails apart instead.
Here is the thread about the gasket...
