Well the LS6 intake is worth 5-10 and the headers are another 7-15hp, neither of which the LS2 doesnt have the advantage of.
I dont even know which one was which, but the blue/purple one was having valvetrain issues it looks like at about 5200+ RPM
Plus they probably werent done on the same day....You cant draw many conclusions other that the purple one was having issues at 5200....

I'm running a production LS2 block, good internals, block filler (hardblok) and pinned the mains...making ~1600 hp
My 06 with a CAI, tune and full catted magnaflow exhaust put down 380/386. The same mods, minus cats on my 01 SS came out to be 352/356, just for reference.
The only thing that blows on the LS2 is the intake manifold itself. With some work, it can perform but even then, a 90mm on an LS6 intake will blow it away. As was already said, 243 heads, 01 LS6 camshaft, larger bore, etc. etc.
