I would like the answer to this question also. It seems that 97-98 used a shim and small seal, and the later heads had a one piece combination seal/shim.
If anyone knows NAPA part numbers, or better places besides GM, please post them.

GM part numbers :

'02 LS-6 Intake stem seal, PN 12482063
'02 LS-6 Exhaust stem seal, PN 12482062

What I would like to know is can I use these with '98 LS-1 heads. Does LS-1 hotcam package include one piece LS-6 seal/seats ?

They are not the same as regular small block seals. They are smaller due to smaller valve stem size.
