Guys, you're over-thinking this one! Just because the methods were crude, they were effective, and thousands of us oldtimers changed timing gears without going to heroic methods. If you're worried about driving the cam out the back of the engine (very rare happening) take the fuel pump off and have a helper use a big pry bar to hold the cam forward while you drive the gear on. Heat the hub, use a big socket as a driver, and pound it on there with a BFH. Trust me, it works!
No, the cam is not hardened, and it would be possible to drill & tap for a push tool. Maybe I'll make a drill/tap guide and a pusher for cam gears like I did for drilling crankshafts!
