I currently own a coupe and want to get a Z06 but I am scared to death of the whole cylinder head issues.Is the situation so bad that you wished you would have bought a GS?

No and never.

That is, no the situation isnt "so bad" if you address the valves and "never wished" i bought a gs.

I wanted Z06 427. Period. Go for it!

Hmmm.. Buy a GS (heavier, slower, lower tech, hate the front fenders, poser factor) or spend $1500 to re-do the cylinder heads..

You can assume the answer..

I have never wished I had bought a Grand Sport.

Fine question to ask in a Z06 forum. You could guess the answers.

Absolutely nothing to be scared of once you understand the situation. Address the issue, and enjoy the car. Every time I hit the start button and I hear the 427 LS7 roar to life...never once do I wish I had purchased a GS. Owned a C5Z, now a C6Z...we wont talk about the C7Z, and I'm looking forward to what the C8Z brings to the table. No offense intended to other owners...Anything but a Z (or a ZR) is a compromise in my book.

It's just a fact of life that the valve guides are a wear item on the LS7 engines. The scary thing is (and I hesitate to call it scary) is that in the 1% of the cases that they do end up being the cause of an engine failure, it can happen at any time - low miles, high miles, no mods, lots of mods. 99% of us out there will never have an issue, especially since these cars are usually toys and we don't put many miles on them. Just gotta use common sense: if you mod your car, you may experience more wear. So either get them checked properly or just have them R&R'd/refreshed for a minimal cost. Even then you should still check them every once in a while to make sure they're ok. I didn't lose any sleep over it when I bought the car. If you're not willing to spend the money to maintain the car, don't buy it.

please no.

Wouldn't trade for my C6Z....

GS does have some advantages. I would like the auto and removable roof. Making up the power is simple, but adding those to a vette is very costly. So it depends on what you want.

I almost bought a GS but found my ZO6 locally. I was aware of the valve guide issue but it did not stop me. Buy the ZO6.

The possible valve issues haven't made me regret my decision to go Z06 one bit.

After having just bought 4 new tires I can say the head fix was only slightly more expensive. Could have been cheaper than the tires but I splurged on some extras.

*El Ocho*

No, never ever EVER regretted buying a Z06 over a GS.

GS was never even on my radar. For me it was Z06 or nothing!

Hell no.... love the Z... but yea.. most of us will say that... we own Zs

Does a GS have a 427? No? Then no, no regrets. Just replace the cylinder heads. No more issue......

juanvaldez

It is all great 'til you drop a valve. Have y'all read the thread about the extended warranty fight?

fattiremike

That's why you replace the cylinder heads! Screw warranty companies. A warranty will cost you what a set of heads cost, or more.

Nope...never looked back. Had a 2005 coupe that I absolutely loved. Traded it for a 2006 Z06, took a beating on the deal, but drove away with a grin on my face. 6 months later, spent a few $$$ on heads, headers, cam, tune. Now, just can't seem to part with it, even though I hardly drive it. But when I do, its absolutely the most fun you can have with your clothes on. I promise.

Dont be a *****

Or buy one that has already had the heads addressed. Lots on the forum in that fashion (Including mine, shameless plug)
