I guess I'm talking about the guide and tensioners. To be honest I don't really know, I'm just trying to keep my wife's car from grenading....
I posted the question after reading this on the flat 6 website:
"Replace vario-cam wear pads and the 4th and 5th timing chains at 40K miles if your car is an 01 or earlier 996 or an 02 or earlier Boxster." ( http://www.flat6innovations.com/pre-failure-directives)

You should have the cam timing deviation checked before the IMS bearing upgrade & then after to be sure it has not degraded & judge condition of other internal wear parts that effect cam timing. You should also have them install new upgraded IMS chain tensioner. These are inexpensive preventive maintenance steps.
