The valve springs are supposed to be good for .570-.580 lift but the ASA is only .525 so I thought it'd be a good time to shim the springs up. Any idea how much I can shim these springs? What is coil bind at on LS6 springs?

It is not necessary to shim 02+ LS6 springs w/ an ASA cam and stock rockers.

What I was actually thinking about doing was running Ti keepers from nascar engines. They are the same degree as the LS1's but the key position is lower down, which about .030 lower. This will have the same effect as a .030 shim.

Why do you think you need to shim w/ .525 lift?

I don't. I'm trying to use a retainer lock that has its ridge .030 higher on the ridge then stock, essentially making a .030 shim. Doing this will bump spring pressure and will give a much lighter valvetrain.

I am not willing to accept that my tiny locks weigh twice as much as my valve spring retainers so I'm looking for a way around it.
