Default 2001 vs 2002 stock LS6 Heads?

What are the differences between 2001 and 2002 LS6 heads? Are the valve springs the only difference? What year did they start using lightweight intake and sodium filled exhaust valves?

I am not positive, the valve springs might also be different.

If they are yellow springs than they are the light weight valves.
