Maximum Lift for stock L98 head

Does anybody know what is the highest usable lift you can get out of a stock L98 head. I am guessing around .500 Or what is there maximum flow potential?

the limiting factor would be the springs and the valve guides, i'd say more in the .47 range. change springs, add screw in studs and mill the valve guides and yuo can run a lot more cam than most people would want

okay since I have 1:6 ratio rockers on my car now then I am pretty close to the limit? I changed my springs and valve seals when I did rockers.
