Honestly it probably will not be hard to jet at all.
I would first remove the boysen quick crap cover. They are junk and going to cause you problems.
Get the directions from JD again, and start at his base line. Many times a modified engine is more volumetrically efficient so you will lean out your jetting. You dont always go richer! Keep that in mind
