[Zslash28]

Seems to be alot of concerns regarding the LS7 head issue and our Z/28s. I would like this thread to be where we capture only those cars that have had one of the following;
1. Any failed factory installed LS7 engine.
2. Any dropped valve resulting in GM repair.
3. Any car that had heads replaced,
and the heads failed valve inspection.

Please provide info as to what led to the failure if known. If the failure mode is unknown, please state so.

Also, for the sake of keeping this on topic, only post info on known failed Z/28 LS7s, or Z/28 heads that failed valve inspection. I dont care about the Corvettes, or "maybe, might, could" assumptions on the Z/28 LS7 heads being suspect. Lets stick to facts, and real events, not 2nd or 3rd hand stories.
