Now my next question is about the water jackets. I haven’t planed on pulling the cylinders because the compression is good (both in the mid 90s) but I dont see an easy way to clean off the rust and scaling from the outside of the cylinder heads and the inside of the water jackets without removing them. Does anyone have any suggestions for me on how to go about getting all of that crap out of there while keeping the crankcase together? If I have to take the heads off I would go ahead and hone it and put new rings in but if I can avoid it I would like to.

Thank you all again for you help

Hopefully one of the many with more experience will chime in here. Personally with compression as good as what you have, I would hate to pull the cylinders apart.
