pidjones said:And to pull the dowel pins without damage (except possibly to the dowel pins); find a drill bit that you can just fit the shank into them, put it inside the dowel while you grip them with pliers. This keeps from collapsing the pin and gouging the inside of the case/jugs/head.
I find that a large EZ out will usually get them out. Sometimes they need warming a to help break teh grip and in rare cases they need to be dragged out kicking and screaming with a pair of vice grips
