"The charge enters the combustion chambers via titanium intake valves that measure 2.16 inches (55 mm) in diameter. Spent gases exit the chambers through 1.59-inch (40.4 mm) hollow stem sodium-filled exhaust valves. The titanium intake and sodium-filled exhaust valves are used for their lightweight and high-rpm capability."

I'm telling you right now, if you think 5w30 is enough to handle 230-250 deg oil temp, think again...hence why 15w50 is used by guys doing road course...

Did you get an entire new motor(including Super Charger and belt driven accessories, or did GM get you a new block and heads and bolt on the accessories from the faulty engine?
I would also guess we will not see as many failures on the ZR1 as the
z06 as their are less ZR1's made and the percentage of ZR1 owners that track their cars is far less then the percentage of Z06 owners that track their cars.
Well I did 
back on May 30th, was washing my ZR1 in the drive way, had a few people stop by to take a peek and hear the supercharger, only to have it embarrass me by dropping #7 exhaust valve and putting out more white smoke then a mosquito sprayer on steroids 
I was told I am the very 1st ZR1 owner to have this problem, am I truly alone out here? The Z06 drop valve syndrome lives on! 
Can elaborate story , and answer all questions at a later time, just wanted to get thread started and see what response I get.

Was told a new (complete) eng was ordered , however GM sent a long block , supercharger , intake manifold , charge coolers etc, separately ? Essentially everthing is new , just needed some assembly . 
Only componants re-used were water pump , alt, p/s pump, etc. They also replaced "everything" that oil touches ( tank ,all hose's ,cooler , etc ) Not to mention also confiscating ECM , BCM , and of course the famous "black box". Overall very pleased with outcome . In regards to your second paragraph , this had nothing to do with tracking the car , and it shouldn't ! This "supercar" was made to be tracked , this was / is clearly a manufacturing defect !

Although, I'd let 'em fix it, then trade her in.
