Some say it isnt important, I would say yes make sure its fairly balanced as its a big lump to be spinning out of balance hung on the end of the output shaft.
But any good machine shop using a lathe wont throw the balance out :)


.....And use an indexing chuck on the mill to drill the holes.

The other option is drill and lathe the original pulley to lose weight.
I was amazed how much weight you can actually shed from a standard pulley with a bit of judicious trimming :)
