Because a stud snapped off in my head, I decided to pull the motor and have the head machined.
It took me and a friend just 45 minutes to drop the motor.
Before I pull the head, what parts should I have on hand to replace during reinstallation?
I have the repair manual but it wasn't very clear on what needs to be changed.

Thanks

I haven't done a head... So perhaps someone else could review this list...

Typically though, you're going to want to replace the head gasket. You may also wish to have a spare valve cover gasket, and possibly a spare PCV cover gasket. You should also have engine assembly lube handy.

And while you're at it you might as well replace the milk in the handlebars. Don't use powdered.

New head gasket.  I attempted to reuse the old one and spray copper on it, it didn't work.  I reused all other gasket and they sealed fine.  A gasket kit would be nice but I couldn't find one at the time I did mine.  Main concerns for sealing for me was the head gasket, the o-ring washers that go with head gasket and the bottom cylinder gasket.  And be a good time to replace valve stem seals

Make sure you don't forget the o-rings that let the top end get oil pressure!
