I think the only difference is in the (exhaust?) valves, they're hollow stem/sodium filled on the LS6s but not on the LS2 versions, I think.

Nope, they're a great budget upgrade. I'm looking into putting them on my Camaro too.

They are an excellent upgrade. We can do an assembled set with non sodium valves for $525.00 per pair. We also offer a set CNC ported 243's with stock valves and Patriot Gold springs for $1095.00.
