Comparing the 01 LS6 to the 02 LS6 these changes were noted:
The 02 used hollow stem valves, higher lift cam shaft, a lower restriction mass air flow sensor, a lower restriction air cleaner design, and eliminated the PUP converter from the exhaust system.
There may be other changes as well.:thumbsup:
