Frosty 
Not sure if anyone else has done this but I did it by accident (Wasent reading instructions when installing) and it ended up working exceedingly well. I was able to run a 3.4 ssm90 pully with no belt slip whatsoever.
The standoff and pully are supposed to replace the coil pack bracket stud on the left. Instead i threaded it into the extra threaded hole in the head / bracket.
Below is zzps method.
Some people were pming me about seeing it actually working so heres a video.
Edit: Video of it working with a 3.4 pully.
Also the belt im using with a 3.4 pully is a K060956 which is slightly longer then the belt zzp recomends normally with their idler setup.
