Ok guy's, I was lashing the valves on the Z3 head today and happened to notice that the upper cam chain guide looked different to the one on the bench from the A2 head. The one on the engine is for the K20Z3(06'-07'Si) and it bolts onto the A2 and A3 head as well.

So next time the VC comes off add this for a added piece of mind for your high RPM ventures. Part# 14540-RWC-A02 (updated part# for 07' Z3 head)

The A2/A3 upper chain guide is in my hand, notice the shorter length of the plastic guide!

The 07 CRV has a different part number for the upper cam chain guide however the 07 accord has the same part number. Just thought I would look for the hell of it not sure if it makes a difference or not.
