I’ve seen no info ( I’ve read just about everything there is to read ) sopporting this. There are several documented cases of 2011+ zo6 vettes with dropped valves. Look on the corvette forum. Also I’ve seen no evidence anything was corrected on the Z/28. If you think gm corrected the issue, your gambling with around 20k $ including labor if your not the wrench type. My plan is to do a full inspection once my warranty is out. I purchased this car well knowing I will most likely need to fix the heads after warranty is up. It’s a real issue, gm has 100% dropped the ball on.
