Purchasing a Z06 - chances of issues with LS7??

I traded in my 2013 Camaro ZL1 (600 RWHP) for a low mileage 2008 Z06...love the C6 Z appears to be all stock and it's much faster than the ZL1. That LS7 pulls like mad. I've read about guys getting the heads done and being out of spec again within a few thousand miles. I've also read, on the forum, about a guy who got his heads back after being re done and they were out of spec. Once you drive one and feel that 427 you won't care about anything you have read...you will want it..lol. For now I'm just going to enjoy my Z. Before you buy a base C6 look at a C5 Z06. I have one of those also and love it! Good luck.

Don't think twice about it, get a Z06 and a have a blast. Buy a GMEPP warranty and drive the car. My 2008 is untouched for 11 years now.. Miles of smiles...

I have a 06Z with 55k miles an have done my guides thing 2x's. My buddy with an 07Z has 90k miles an has not even had the red plastic valve covers off his car. You never know though.

who did the guides the first and second time? How long did they last before they were out of spec?
#26
First time was at 27k miles in 2013. I dont want to say who, but it was bronze guides with solid stainless exhaust valves. 2nd time was AHP. I went with the stage 4 heads with moldstar guides an hollow stem exhaust valves at 54k miles a few months ago.

Yes, that was GM's official response, but we all know the admitted machining problem is not the only cause of excessive guide wear. If it was, then only those few years would experience excessive guide wear but it is a well known fact that all years are affected by excessive guide wear. Don't bury your head in the sand and think you are safe just because you are outside the years GM said they had a machining problem.

Wow thank you so much for all the advice guys, very much appreciated! After spending the weekend watching Z06 vids on youtube and talking to my local performance shop about a getting the heads refurbished I'm pretty sure I want a Z06. My local shop says they send the heads to American Heritage to be redone (looks like there package is about $1400) then re-installs them. Including labor what do you guys think i can expect price-wise for the whole heads job done? Maybe $3000?
Thanks!
Thanks!

I’d take the middle man out....just go directly to Kohle and get your heads done, bring them to the shop for install if your not gonna do it your self....you can easily remove them yourself and AHP’s kit is designed around DIY so you could do the install yourself if you wanted to, if your not comfortable no big deal I don’t blame you for that, but removing is easy day.
Also I just got the total quote from my local shop which is $3100 for labor, parts, everything...a lot of money for no power gain lol.

Good advice, i will definitely consider that thank you. I mean i have experience working on cars but that extends to just doing headers, intakes, brake jobs etc...never come close to removing heads before...

But...if that is not in your budget, no power increase is better than 100% power decrease when the valve drops.

That's a little on the high side, IMO. At least compared to what my labor was and that was also installing the AHP 110 camshaft and a tune...which I'd strongly recommend if you want to make more great usable power with killer driveabilityty.
