That explains a lot

yes but you have the heat up the entire head in an oven, to about 500 deg.
then take an air hammer with the correct bit and drive them out. After that is complete you have to drive the new guides in with lube before the head decreases in heat....My suggestion is take it to a machine shop.:wrench:
