Second thoughts
Jeez guy's, I was pretty fired up about getting a Z06, until I read through 70 pages regarding the valve guide issue. Can someone give me a synopsis on whether or not GM is stepping up to the plate? If they don't think that leaving this issue unresolved is going to cost them in sales, they are not listening.

Don't let it ruin your experience. It is a bit overblown in my opinion. Get one with a warranty, or if you are paranoid about it then get the heads re-worked by a reputable shop, the cars are a blast to drive and own. I came from a base C6 - no regrets!!
It is an amazing machine!

I do need to confess though that I do know one person (not forum) that has had a dropped valve on his Z. Plus I did choose to have my heads addressed even though mine showed no signs of wear. So, do take that into consideration when deciding on this car. I knew of this topic before I got mine, not regretting my decision.

My first vette was a 2008 coupe.
I had a Z06 for a short while and now have a 427 (same engine)
It took a little while to get used to the sewing machine click.
I am still getting used to the awsome power in a wide body.
I too think the valve issues are blown out of proportion...the biggest vette dealer in Alberta told me they have had no valve issues with anyone's stock 427.

I guess I should have gone back and done the math and see how much more than 18% they represented...maybe it's just a feeling anomaly.

If you can afford a Z06, then get it. I wouldn't let it worry you. And if you buy one, the first thing you can do is go to a shop and have them take a look at the valves. It will be like 2 hours of labor max but will give you peace of mind.
