These are the differences between the z06s.
From '01 to '02 --> revised intake, slightly different cam, piston ring fix (oil consumption issue), HUD standard equipment -upgraded to 405hp from 385
From '02 to '03 --> control arm bushing upgrade (problem with slipping control arms on '01s and '02s), Bilstein shocks as standard equipment, fuel pump relocation
From '03 to '04 --> valve spring upgrade, stiffer Sachs shocks, further bushing upgrades, different t-stat housing
