correct me if im wrong, but arnt the h22 and h23 the same, i ordered a mugen 160 and it is bigger the my other one, the paper it came with (in japanese) says accords preludes bb2 and bb4 as well as others, i know they didnt have h23 non vtec over there but still.... wtf

 

H23, F22, F23 are all the same. H22 is bigger and is incompatable with the other stuff.
