LS/GSR/B16 blocks have issues with sleeve reliability when revved past 9K. Admittedly it's not a big one and those cars were probably untuned and flogged on. Siamesed sleeve B20s... eh, after seeing what meticulous people like B20Pete do with B20s, it makes me wonder if those blocks aren't great budget NA blocks if you know what you're doing... unlike a lot of people.

Single piece? With N/A it doesn't seem like you'd have any issues with sleeve movement at high rpms.

The liners are as thin as 0.060" thick, they are strong but not resilient. You can make a lot of power on them, but don's subject them to harmonics or detonation.
If you are still not buying it... frankly I'd rather you thought for yourself... look at the VEMS wiki for their writeup on hos knock is detected via a KS. The resonant frequency the sensor looks for is the one that the block sings at under detonation, and that frequency is a function of the bore diameter. It all dovetails convincingly.

Re: How about a REAL discussion about LS rod bolts?
Are you saying before major damage would be done, the knock would be detected because the lower amplitude (which would still be detected by the ks) is associated with less "severe" knock?
