The issue is not about replicating the problem. The issue is having a tech who has little to no experience with Corvette tear apart the engine of a brand new C8 with 20 miles on it. It sounds like the OP decided to take it to another dealer that has way more experience with Corvette. I think that's a smart move.
OP, I would have Chevy tow the car to the dealer on their dime. I agree above, you should really not be driving the car. Do not give GM any reason to deny a warranty claim, and believe me, I would not put it past them to try and blame you and charge you for a new engine.

Its hard to believe they cant chase down a code . There has to be one and theres a defined troubleshooting procedure for each code in the service manual. Sorry your having this problem . Dealer incompetence is inexcusable and the thing i worry about the most with the car.
If you have the car back in your possession take a code reader, read and post he code. Maybe the forum can help. I have a service manual that lists all the codes for all of the systems .Happy to share carl

If the broken spring was seated correctly I’m figuring defective part. It sucks but it happens. If it wasn’t seated correctly it may have stacked and broken. If that’s the case the valve guide is probably damaged also.

I'm not a C8 tech and I don't even play one on TV.... But if the plug is sparking the next logical step is to check the cylinder compression. As a matter of fact you don't even have to be a C8 tech since all internal combustion engines have worked the same since the 1800's. Piston go up, valves close, pressure goes up. So simple even a GM manager can understand this.

well, the car came from transport with 2 miles on the odometer and when I went took delivery it had 12. I was told the Corvette tech had to drive it for 10 miles. That it was regular procedure. Is that right? I’m thinking maybe he drove it too hard and caused this issue?

Some of these cars are time bombs.

And if one spring is bad, the rest may be too since they came from the same lot number most likely.

I think we are definitely beta testers. Our Supra is going on 3k miles trouble free

Or maybe to fix the 4 million recalls they constantly have.

Unfortunately GM is too busy filing lawsuits against their dealerships and doesn't have enough resources to put in a working quality control system or certify techs to work on their products.
The stupidity at GM amazes me every day. Every day you see new C8 Corvettes dropping dead left and right only after a handful of miles and yet GM is suing a Chevy dealership in Iowa for adding FCA products to their GM dealership since FCA cars "tarnishes" GM’s image. The dealership group in Iowa is simply trying to cut overhead and stay in business. Any corporation with a lick of sense would be a lot more worried about their crappy quality being a bigger "tarnishing" factor than having a Jeep sitting next to a Camaro.
GM could care less how it's dealerships screw over potential GM customers. But put a Jeep next to a Camaro and you'll feel the wrath of GM attorneys in a heart beat!
This kind of idiotic behavior by GM management explains why GM's stock price will never exceed its initial IPO back in 2010.
