Weird, I posted an update last Friday...anyway. I finally got my car back on Friday. Thursday night they called me to come watch the initial startup. It fired right up, and at first I thought they had already done it, but then the white smoke from the residual oil in the exhaust started pouring out of the tailpipe. Everything seems great, although I'm hearing a clunking sound at very low speed turns. Might have to have them look it over...it didn't do that before. Great having it back though!

It's not the engine...I thought it might be the tires, I've read that before, but it seems like I can feel it in the steering. They took the front end off when they put in the new motor, and I'm just worried something isn't right.

Pretty sure it is normal but I guess it wouldn't hurt to have them check it out. The wide tires will skip on slow turns, and the colder the temp the more pronounced it gets.

Just did this on my Z06 this past weekend; even without a lift it's not that hard. The hardest part is getting your Z06 lifted and level. The C7 Z51, Z06, and ZR1's all have dry sumps as well, as the procedure is the same. I knew the dry sump procedure but I couldn't speak to the "why" behind having to check when warm and all, so I looked it up and can now speak to this. I'm sharing this for others. As mentioned above, you don't have to change your own oil, just now how it is done, and preferably, why it is done this way.

These vehicles have a racetrack-ready dry sump engine lubrication system. This high-performance system operates differently than a standard engine lubrication system and requires a special procedure when checking the engine oil level. Follow this procedure closely.
The engine oil level must be checked when the engine is warm. Cold oil level in the dry sump tank may not indicate the actual amount of oil in the system.
With this system, engine oil is contained in an external tank, separate from the engine. Under normal operating conditions, the oil pan under the engine does not store any oil. If the vehicle has been parked for an extended period without the engine being started, some oil will seep back into the oil pan, reducing the amount of oil held in the dry sump tank and there could be no engine oil at all showing on the dipstick. This is normal since the dipstick is designed to read the engine oil level only after the engine has run long enough to reach normal operating temperature.
Do not add engine oil based on cold engine dipstick readings. The engine oil level on the dipstick will also be inaccurate if checked while the engine is running.
1. To obtain an accurate engine oil level reading, warm up the engine to at least 80°C (175°F). Cold oil will not give a correct oil level reading.
2. Once the engine is warm, turn off the engine. Checking the oil while the engine is running will result in an incorrect oil level reading.
3. Check the oil level between five and 10 minutes after the engine is shut down.
4. Remove the dipstick from the external engine oil tank and clean it with a lint-free paper towel or a cloth. Re-insert the dipstick into the externa oil tank, pushing it all the way in until it stops.
5. Remove the dipstick from the oil tank and read the level on the cross-hatched area. If the oil is below the cross-hatched area at the tip of the dipstick, add 1 L (1 qt) of the recommended oil through the oil fill cap opening in the oil tank and then recheck the level.

I had my oil changed at a local chevrolet dealership, and was talking to the service manager. I asked him if his tech knows what he is doing, and if he knows about the dry sump cars. He said yes, they have a guy specifically trained to work on corvettes only, and that was the tech that was to change my oil. I got the car back, and in the parking lot, i pulled the passenger coil cover and magically there were plier marks on the valve cover plug. I went back inside and pulled the service manager out to show him. He apologized and offered a free oil change. I couldnt hold it in. I busted out laughing and said "you think I'm gunna let yall work on my car ever again? You are out of your freaking mind."
Now OP If you had your heads repaired already, to save you money I would use the repaired heads. Thats unless they will pay to have the new ones repaired.

Okay, so i'll pose the question on everybody else's mind...
Will you take the car back to that shop for oil changes?
Happy for you buddy.... Glad things worked out.

Honestly, I'm happy with the outcome, but it didn't come without a lot of stress. After the initial 2 weeks of BSing me about stuff, they stepped up, and then it was 2 weeks of waiting for parts etc. In the end, my car is better than before, so I can't complain about that. I feel bad for the guy that messed up, but he'll never see any of my cars again. I have a newly installed crate motor, 3/100K warranty, and after it finally burned off the excess oil from the exhaust, it's perfect. Didn't do any mods (i.e. heads) as it would void the warranty (ironic right).

Wow, absolute best outcome you could imagine from this whole ordeal! Glad to hear she's up and running. Now it's time to either (A) do your own oil changes or (B) become "that guy" EVERY time you go to have your oil changed anywhere...even dealerships. I'd reiterate not to take it lightly, but somehow, I have a feeling you won't.
