I'm sorry, I should've been more clear. I had the factory heads CNC'd, bronze valve guides, new valves, rocker arms, push rods etc.

Gary, saw this in the FS section... https://www.corvetteforum.com/forums...ls9-heads.html

Doesn't look like he's on your list.

Mike,

thanks...I've updated the list.

The moderators removed the "sticky" from this thread when the ZR1 & Z06 sub-forums were merged...and I have been unable to get them to restore it.

Appreciate your helping me keep it alive...the list has good, important information for all of us keeping tabs on the LS9 (and by inference LS7) valvetrain matters, and I am committed to maintaining it.

Gary

Yeah, I thought this was a sticky. More than a few things were screwed up with the merge...hopefully things will get sorted out eventually.

Default Ls9 guides

Just had a friend put a cam in his I think 30000 mile ls9. He stated he did a wiggle test and they all the checked out ok.It was a 2010 by the way.

Unfortunately, the "wiggle test" is not as accurate as a bore gauge w/mic...the wiggle test is only an indicator (IMO).
Based on the reports on the list, it would not surprise me if some of those LS9 intake valves are out-of-spec...
