550 and 650 pistons are different. its crown is shaped different, but same diameter and piston rings are the same 450,550,650. its all in the top
 
You sure John??? they are same part number from wossner but i see what you mean as the old one is concave the new one has a high flat shape looks thinner and not as strong as oem.
