I had Lethal performance rebuild my heads replacing the guides, exhaust valves, install high lift springs, polish and inspect everything else. GM won't pay for your motor if you drop a valve. Period.

Just factor in the cost of getting the heads repaired into the cost of the car. When the heads are done you can start to enjoy the car with peace of mind.

After reading this thread I am a bit concerned. My 07 z06 has 40k miles...39k of them babied miles as my father commuted in the car to work 100% highway. I did a two day track day last year and planning on 4-6 days this year. Car is 100% stock and regular oil changes done. Any advice?

I filed a complaint just now. My car at 37xxx miles already had an engine replaced before I owned it at 22xxx miles. For me it's just a matter of time, and I know it.
Hopefully I can get the funds together for AI or Reher-Morrison (Darin Morgan) to rework my heads.

When my engine failed it did not lock up. It just quit running. Pre repair diagnosis showed it threw a manifold vacuum code at 2300 rpm which must have happened after the engine quit running since I disengaged the clutch around 6800 rpm and the tach just dropped to zero. From that point it took about 1/3 of a mile without PS or PB to get the car stopped in a safe run off area. I would have much preferred trying to steer a Cobalt without PS than a Vette with wide tires. My in car video which is posted on the forum captures it nicely.

Mine went with 16,750 miles, albeit EXTREMELY hard miles. Been full-time autocross car from day 1 home from the museum. Hoping to fire up the new engine this weekend. Heads/Cam/Fast LSXR 102 Intake and 102 throttle body/Tune/Long tube catless headers. Car will be down to 2,900 pounds shortly too.

Has anyone concluded that all years are affected. My 06 has 22k on it and it runs good but I swear I hear valve or lifter tick when the radio is off and just driving Dow the road. Not sure if this is an issue or not or I just hear the engine more because the car has no sound deadening.
I am worried but I am not in a financial state to put money into this car like that.
Anyone else hear faint ticking while just cruising?

If you have the warrantee then you really don't want to get a new engine. The engines are very good, it's the heads that are the Achilles heal. If you don't then why gamble on 20k $ versus 2-3K $ and peace of mind. Get it measured!
