I will respectfully disagree with this statement. There is a definite valve guide issue on the LS7. It’s a ticking time bomb with the oem heads on it. Again, not sure if this problem exists with the later Z28s (very low production #s) but it is in fact a huge issue on 2006-13 Corvettes. My buddys C6 Z06 grenaded at 20k miles. My very early build 2006 pilot Z06 made it to 50k before grenading. It’s the luck of the draw.
