Your best bet is to get a set of v-blocks, a degree wheel, dial indicator, and index a set of cams yourself. The 4g info should be enough to verify what you have but if you want it accurate... you have some more work ahead of you.
I would bet that the 4g and 5g cams aren't THAT different. Probably a few degrees duration and maybe a few thou lift.
You have to watch cam specs; some will spec duration at in. of valve lift, in. of lobe lift, and all by varying amounts.

It depends what information you're going after. If you want the shape of the lobe on the camshaft, then the V-blocks and dial indicator will be fine. If the valve lift profile is necessary, then taking measurements on the assembled valvetrain is necessary. The locations of the camshaft centerbore, follower radius center, valve tip, and valve angle will all determine the actual valve lift.
