Valve springs and a Timing Chain looks like you are 98% to the cam right

As the others said. Ls2 chain and the ls6 blue or yellow springs. And possibly valve stem seals. We have the comp spring compressor tool also. It makes the job 10x easier. Some people will also put in an oil pump at the same time.
Also dont forget the balancer installer. Or a handy set of oven mitts!

Only the first/early gen LS6 valve springs have premature failures. I don't know of many/ if any newer LS6 valve spring failures on a stock engine.

My cylinder 5 intake spring broke at 87k miles or so. Not sure if you classify that as early failure or not. To me that doesn't seem bad, almost 90k miles out of a spring. But I would expect a stock spring with stock cam and valvetrain to last a bit longer.

Honestly ls6 yellow or blue springs should not be used on anything larger than a stock cam. They sure dont have the pressure and the new blue springs have a shorter rated max lift. I would upgrade to the Pac 1218/1518 or the Manley beehives if you want a true and good long life spring. IF you are lookin at upgrading.

Though I haven't had them tested, I believe at least 1 of my stock 104K LS6 valvesprings is at least extremely fatigued. When I pulled the heads I didn't see any breaks, but the engine was displaying the symptoms of having a broken valvespring.
At 104K, there was also an extreme amount of slack in the stock chain. At least .5" of deflection.

I haven't been into an LS but have done plenty of timing chain replacements on older GM V-8s with the nylon toothed timing chain gears that would actually jump time when the nylon wore out. This is what I call a failure and was the reason many older cars did the timing chain replacement as a preventive maintenance measure.
As far as .5" of slack, based on what I've seen in the past, I wouldn't be to worried about that and won't be digging into a perfectly good running engine unless the LS engine series has been known to be adversely affected by it.

I am going to just toss some yellow springs back in and seals. Should I replace the keepers also or will they be ok? These the right seals and keepers for the ls6?

PS there is nothing different from a V and any other LS engine out there. Since they are most similar to the vettes, there are quite a few references about them stretching though.
