There has been no hard evidence the z/28 ls7’s are any less prone to the valve issue then the zo6’s. Budget having the heads fixed if you want a z/28 IMO. Other members will chime in saying gm fixed the issue with the heads, but with NO supporting evidence. I’ve read everything there is to read about the issue and nothing has convinced me it’s fixed. My car is out of warranty in jan 2020, I will be pulling heads for inspection and most likely off to be fixed at that time.
