Distance between cylinder walls on 08
 

I am playing with the thought of innstalling a big bore kit, some head work and increase compretion to around 13:1 or more. But I have heard that the cylinder walls is extreamly thin on the 08+ models, so by innstalling a big bore kit will make them even thinner. So can anyone tell me what is the exact distans between each cyllinder on the 08+ models?
