Default Best valves for this setup?

I may have a set of slightly used 2002 LS6 valves. I am building up a set of heads for a truck 5.3 motor.

Patriot Stage I 5.3 heads milled .040"
I want to run a 2.0" intake and 1.55" exhaust valves.

I may run nitrous in the future, which is why I was wary about the LS6 valves. I don't want to burn a valve. It will not be over a 150 wet shot, though.

I was looking at going with Ferrea valves if I don't go with the LS6 ones. I imagine the LS6 valves would be best for power/reliability because of their weight. Any ideas?

Would they flow more then a LS6 valve with a backcut? I know they would have to weigh more.

Well, I ended up buying LS6 valves. I've always thought the lighter the valvetrain, the better and they come in the sizes I want. Hope they do alright.
