Which Valvesprings for boosted STOCK LS2?
I have been thinking of upgrading the valvesprings for added safety of the my valvetrain under boost and high RPM's! I have no plan of putting in a higher lift cam as the stock cam is working great, I mainly dont want to over srping the engine.... all I want is a good set of vs's to allow the engine to rev a little higher at this power level!
Thanks
Stephen!

What kind of rpms do you guys think would be safe to stay under with stock bottom end as well? If could rev to 7k it would help my gearing issue a LOT!

Man it's crazy to see the steel retainers are about the same as the other titanium. Those super 7 locks are CHUNKY 
I run the titanium Tooley ones and it's a nice kit, but for the money and a little more weight on the valvetrain I'd rock those steel retainer ones on anything thats not a crazy cam or high boost/harsh cam deal for sure.

I wish I knew what valve springs and valves my dad had installed before I got the car. I hit the 6500 rev limiter like a wall one time in 2nd gear.
I would love to knock the limiter up to 7k just so I'm right at 60mph in 1st.
