Think im getting some valve float or maybe have a broken spring. So I have a good excuse to swap them out.

Stock cam? If you want an upgrade, I'd just run the PAC1218:

We really need to know more about the combo! What head is it (or more importantly what valve in the heads)? What are the cam specs?

The motor is completely stock. Stock heads/cam I do have a set of 317 heads/ls6 cam that I plan on adding over winter.
So which spring will work for my current setup, and will also work with the future setup 317 heads/ls6 cam?

Duals of any sort would be overkill on a stock or LS6 cam. PAC 1218 or equivalent would be my recommendation. You could use LS6 springs for a cheaper alternative, but I personally would go with the PAC1218 or Comp 918. Any of them will use your stock retainers and locks.

In my opinion, I don't see why that boost level would be a problem at all.
