How big of a cam?

How big of a cam can i run on a 5.3 without upgrading the stock valvetrain I.e: springs pushrods and rocker arms? is a .588 lift cam too much?

I'm running LS6 springs with 525/532 lift.
I believe the stockers only go up to like .500 lift and can't handle the lobe design of most aftermarket cams.

Stock cam is as big as you can go on stock springs.
