.475 lift would be a safe bet.
To figure out your max lift measure your installed height for the valve springs then measure the valve springs fully compressed. Subract the smaller number from the larger number then subtract .080 per coil. That should be your max lift for the springs. When you install a new cam you should also change the springs so that they have the proper pressure for the cam.
