I guess my first question is what hammered the piston? Keep in mind that I do not see what you see and surface scratches to you may not be to me. I would look the head over very carefully looking for abnormalties. You can put some thin liquid eg. carb cleaner in the intake and exhaust runners and see if it leaks past the valves and if so how badly.I do have 61mm cylinders for that engine with the 3 1/8 spacing of the studs. To see what you got measure diagnally across two studs center to center, it will either be 3" or 3 18". The kit I have however will require boring of the case which I can do. Give me some more specifics such as mentioned above and if possible some good pictures of the piston , head, and cylinder. Also where are you located?
