    about the 800 cylinders: if i remember correctly i recall reading somewhere about people running the 800 cylinders on the 1200-- they will work but they`re a bit aggressive and seem to run really hot... maybe someone else can chime in

    800, 1200, 1300 will all bolt up. 800 exhaust port is different and way too high for single pipe.

    just stick with stock 1200 cylinders (66-V) and keep your live simple
    800 cylinder 66-E as mentioned have different port height
