Well I don't know my math at all so no clue how you figured all that stuff out but anyways I wouldn't cut any coils. Get the right height coil because especially with that motor you have in there with that power and weight cutting the coils is not good. Not supposed to cut more than 2 coils or so the most but really your not supposed to cut ANY coils. I wouldn't chance it, bring them back and get the correct height.
