You'll also need to upgrade to an all-metal hotend... these can be a pain with a bodwen style printer because they have a very small transition zone, so you can't use very large retraction distances otherwise it jams. On my setup I have to decide to either live with some blobbing and stringing, or turn up retraction and risk a jam.
