I just chucked a rat-tail file in my drill, EASY on the throttle, and made pretty quick work out of it. A light coat of primer on the pushrods in the concerned area, mock it up, turn the engine over a few times... kept power-filing & rechecking until the primer was unblemished.
Having a proper tool would take all the fun out of it!
