Ksr Engine Modify Help

hey everyone iv got a standard KSR-110 and want to modify the engine i see takegawa have 3 different packages i would be very greatful if someone could tell me the performance difference would be between the 15,000 baht 138Cc hyper S stage kit package and the

38,000 baht 138Cc Superhead+R bore up kit i see there are more components but would the performance be such a big difference like the top end or would it just increase the accelleration ?

also anyone know the top end of any of these kits ?

cheers T
