Seen 2 of those "LS3 swap" Z06's here locally on the used market.

@@drewmorg. Yep. More than likely a proper valve job would have prevented total engine destruction.

I had a loser not install lash caps in Nashua New Hampshire. Then went to west coast cylinder heads, what a better experience

I’m very sure he’s going to be doing a lot more than just the heads lol

@@vette2763 I mentioned that seeing how he’s doing donuts and burnouts. Once that valve goes south, it all could’ve been prevented. Not laughing.

@@regsmith7604I don’t think he’s going to be ragging on the car very much more while it’s stock. I do understand valve guide wear is an issue, but a few donuts isn’t going to be the end of the world. I doubt it’ll be stock for long anyways. Not sure why it seems I struck a nerve…

@@vette2763 You’re triggered

@@regsmith7604 lol have a good night

Replace with good aftermarket heads! You can "fix" the factory heads, but I've still seen those fail as well many times. The safest way to address them is go aftermarket heads IMO.

I never thought of pulling the Onstar fuse to help with the battery drain issue on these cars. Mine historically was always questionable after sitting for 10-14 days MAX. It never occurred to me the Onstar is possibly the big draw. I'll have to figure out what fuse that is and see if it helps. One big upgrade I made this year was the battery, and it was a cheap one at that! I took my old battery out (3 years and it was toast after being charged up and down so many times) and brought it down to Walmart to grab a replacement. While I was there, I noticed another "MAX" battery on the shelf that was the same size, but about 3/4"-1" taller, although it had an additional 200 cca. It was even a little cheaper. Since putting that battery in, I have not had a single issue starting the car, even after a couple of weeks, and not one "slow" start when the engine is heat soaked. Total game changer!!! The only two negatives was the terminals were on the other side (but the cables still reached), and the factory hold-down no longer fit. While it would be possible to fab up a new hold-down, I didn't bother yet as the battery is obviously very secure in the factory location, and the cables would prevent it from falling out if it the car were upside down... and honestly, I'd already have big issues if that were the case anyway, lol! Oh, and the battery "flap" still closes with the taller battery, although it's close. But that change has been such a huge improvement over the factory size batteries I've always used, regardless of brand or price! I'll definitely look into finding the OS fuse if that helps the sitting drain issue also!

Which fuse is the onstar one?

@@lifeonmars03 On the C6 its in the passenger foot well. the fuse box panel tells you which one its a red 10 amp mini fuse.

@@ssoffshore5111 For me it was 6 or 7 days which turned into 2. Well see how long it last over the winter im driving to much now during the summer to see.

@@ssoffshore5111 the battery drain on C6 Corvettes is terrible and a major pain in the ass.

What cam and heads?

You clearly have no idea what you talking about...May be check the hotlap of 2012 Z06 vs GT3 RS vs GTR..then make a comment

@@twinturbols9843 ? what are you talking about? i commented on the fact it was called a front engine car which it is not. i would know, i have one in my garage. not one part of the engine is in front of the front axle.

​@KimberKlr my Z06 Is front engine. Not sure why you're saying yours isn't.
