Cost, higher compression, and with a little porting and bigger valves they perform well. I've had mine for 4 years, good hp with a mild cam.

They will give you a higher compression ratio than LS1 heads without milling them.

But you have to do the porting and valve change, as stock, they are smaller than LS1s
