I'm assuming that your decimal place '.' is in the wrong spot in your post? other wise a few are way too tight.

Your correct that all intake shims need to be changed, but I'd also change the exhaust outer shim that you measured at 0.26mm. Make it 0.28mm because it is much better to be loose than tight. If the clearance is too tight you can cause valve seat damage.

Also when you remove cams remember to put a rag in the cam chain hole, you will kick yourself if you drop something down there!
