[misnomer]

Both upper timing chain guides may have been nerfed, I just pulled out my lower upper timing chain guide. THe upper chain has two guides and one tensioner. The chain itself is in more or less an upside down triangle shape with the tensioner on the left, a guide on the right, and a guide on top. Top guide goes for sure, right guide can go as well (but hell, if you have it, go ahead and replace it).

As far as guides and tensioners:

Upper timing chain tensioner
Lower timing chain tensioner
Lower timing chain guide (tension side)
Lower timing chain guide (slack side)

Plus the chains and any other stuff you are going to replace :P
