which is better ?

i might buy a stock cylinder with the sleeve already installed thats why im asking it's far cheaper then the full vito's kit but i would need a head with it then get the big bore gaskets and such i think idk im in the middle of 3 rebuilds and need to get them finished (well actually only 2 atm im decideing what to do with the 3rd one... might do a swap or just part what i can and keep the frame for a spare)
 
the vitos bbk bore starts at 74mm someone correct me if im wrong,


yes thats wrong,
72mm starting point for all BBK's, and you only get 3 overbores, not sure what they are
 
Why not just get a stock jug properly ported?
im thinking about a 240 ported head mod build i have pmed you about the head mod so now im wondering on your porting skills ? are you up for the job this cylinder will need a head could you make me one since i have 3 spare one's?
