z06 heads upgrade

No idea Frank. Different opinions on pulling the valve covers off and doing a wiggle test first. GM swears not all LS7's will have the problem but I don't know. I'm guessing Dave (or someone else experienced with the LS7) would be able to tell you if the wiggle test is accurate in assessing side loading wear, and can also advise ahead of time on what the repair would cost if they need to be replaced. Good Luck and keep us in the loop.

Dave can comment on the length of the job, probably closer to a day than a week. @RaceReadyGarageInc
 
the wiggle test is somewhat irrelevant.
these motors have that inherent problem. just get them done. you WILL save yourself a heartache and a lot of money by replacing the valve guides.
