Chain Tensioner Replacement Clarification

[cornontherob]

So what I've gathered is that it's the ramps in between the camshafts, however I could be wrong and it's actually the long ramps that are tensioned by the hydraulic tensioners. I don't know if starting like this will damage anything in the long run. I also still am not quite sure how to set the tension on the hydraulic tensioners, or where to find the tool to do it.
