For some reason I think what happened will not happen again anytime soon.

Nobody likes the Z06 springs for $65?
The 918's are noisy?
Should I spend the $360 on the titanium springs?
(Plus $100 for the spring tool?)

What makes a valvetrain noisy is improper pushrod length after a cam install, more so than 918 springs. I've got 918's and you can't hear my valvetrain unless you open my hood and stick your ear up to it.
If you are only going to 6K RPM with a ~.550 lift then you'll be fine with '02+ LS6 springs. You could even push it to 6200-6300 if you wanted to, but the higher you go, the more you risk valve float. Less of an issue with the 918's because they have greater seat pressures (open and closed).
I think you're fine on the cam, any of the cams you put up in your poll would be good choices. Think of it this way - the stock cam goes up to 5800 RPM, and it's only 190/191, .45x/.45x, so any of your choices would get you to 6K or 6200. It really is a personal decision.

Just spent the last hour on the phone with Joe Vinci. After talking it all over I went with the ASP Kicker cam and thier titanium springs. He said these will work with stock pushrods and rockers. After I told him I would be shooting for 8#'s of boost on the LQ4 he said the ASP was they way to go. Should have a little chop to it and it pulls from 1900-6000. Also found out I will need a water pump gasket, Crank bolt, Valve seals, Timing cover gasket and seal.
Guess I need to go to the dealership or GMPartsDirect.com. Anybody got part numbers?
CAM SPEC:
DUR @ .050" 210*/218*
LIFT .551 / .551
