Do you heat the castings on the block that the pin goes through then use a air hammer and spray some type of penetrating oil after its been heated? Last thing I would not want to see is a broken casting ear that holds that front pin
 
I use air hammer without heat if air is available. Otherwise a heavy hammer and short, stout punch. They can be stubborn.
