I think you mean 063 heads ??? yes not 068?? Any way they will both be the same the 215 heads are a few years old casting than the 063 supersede the 215 heads. Both 101cc chamber exact same combustion chamber design
NOW some call these heads closed BUT I say they are OPEN chamber (101cc and larger) because they have a QUENCH area still. Closed chamber (98cc and less) HAVE NO QUENCH at all, just a small bath tub chamber tight around the valves.
I would call them the same casting... Might be a temp boss or something changed etc.
