Installing with a proper tool is the best way, or possibly the threaded rod idea mentioned. Basically if you use the install tool you are using ALL of the threads on the crankshaft to install the damper, instead of just a few with the bolt. This allows the damper to be installed in compression against the crank nose when the tool threads stop, instead of a couple threads in tension. A few extra minutes and $25-$30 to rent a tool (which you get back as soon as you are done) is a lot cheaper than having to get your crank machined because threads were ripped out.
I won't even get into tapping with a hammer. Leave that to the Chevy guys...
I have heard an interesting method using boiling water with the damper in it, and an ice pack on the crank nose. Then quickly (with gloves on) slide the damper on. In theory the damper should grow and the crank should shrink enough to slide on. I'd still use anti-seize. Never install a damper dry without some form of lubrication, it will tear up the damper and the crank surface.
