2002 LS6 Valve Seal Replacement Question





12482063 LS Intake Valve Seal Kit
12482062 LS Exhaust Valve Seal Kit
The shop manual mentions something about first design valve spring shim (7) and second design valve stem oil seal and shim assembly (2).
"The first design LS6 application uses a separate copper plated spring shim. A shim of the same design must be installed. A second design seal and shim assembly may be used on later engines. A separate spring shim is not required with the second design seal and shim assembly".
Should I be removing a shim and replacing it with a seal and shim assembly? Do I need any special tools to remove and replace the shim or seals?
