I have a very clean b-20 bottom end. No top end pistons clean walls cleanetc. I am a harley guy and can't leave well enough alone. What would it take to turn this into a b-20 double overhead cam? can it be done? Who can do it? I know that port and polish and also valves.
Thanks in advance for help and advice

B20 is a double overhead cam engine (twin cam for a harley guy).

 

yeah the b20 is a DOHC motor ,it is non vtec though. So if you want you can put a vtec head on it and build the bottom end to handle more compression and have yourself a nice little setup. if it were me though i would just do b20 turbo
