Something's not measuring up right. According to your original post the bore measures 4.046 and the measurement you are coming up with for the piston is 4.055? Sound's like it's time to measure the bore once again. The best way is to use a bore gauge, if you have one. That way you can measure the entire bore length. Stay away from that top ridge as it will measure smaller.
