01-02 LS6 head differences?
I know the cams were different between the two years but I am can't remember if the heads are different.
Are the springs different? Valves etc? I know the 02's have sodium filled valves just curious about the 01's.
I know someone looking for a Z-06 that he is going to swap the cams out as soon as he gets the car. Just wondering if the heads were identical between the two years. If they are he'll pick up an 01 Z-06 and save some cash.

TIA!
