Don't go so fast. One thing to do is to squirt oil in the cylinders, particularly No.2 and see if the compression comes up. If it does, that would possibly indicate bad ring seal. If no change, it might indicate bad valve seal or head gasket seal. The latter two can be remedied without pulling the engine. 25 lb. differential between highest and lowest cylinders is not acceptable in a new rebuild, but if the car is not burning excessive oil you could run with that amount of difference for many years and never know or feel it. I would take it one step at a time and not be in a hurry to pull the engine before it is indicated unless that is just something you want to do or want to rebuild it.
