Still wouldn't hurt to try to turn the motor with it, and see if any play
has developed.

I believe the key isn't good enough, and if the bolt does not keep the hub
clamped tightly against the timing gear, the hub will eventually work it's
way loose.  My problem was that the steel "insert" I used (just a big flat
washer) pulled up against the crank nose instead of against the hub.  But
with aluminum, I'd be more worried that it would eventually distort enough
to relieve the clamping force.  Especially since it's going to expand more
than the bolt every time the motor warms up.
