Are there any other issue that are common on the C6 Z06's that most track guys modify right away for reliability?
If you get an 09+ Z06 you dont have to upgrade oil sump since they have bigger tank

Typical cost is roughly $1800 if you have WCCH port your heads with better exhaust valves and bronze guides. You could also get a set of PRC 265 heads for $3k(ported head, new Ti intake valves, new exhaust valves and guides) and then sell your stock heads for $1200 which nets about the same. Many have gone with this PRC option.

Im not aware of any other issues, perhaps get better brakes but from what i hear stock brakes do the job. I have pushed my car twice this summer on this 120 mile mountain road with crazy turns and brakes held up fine(it was 103+ degrees both days)
