Honda-SOHC

Hi all,newbie here....I've restored three honda CB500s and loved every minute of it,I've now purchased a honda CB750 K1 with a honda britain fairing(two cibies),seat,alloy tank cast alloy wheels,raask rearsets,its been bored out to 860 aswell,the frame is absolutely mint,I also have a shed full of spares for what I think is the donor bike,my question is what the best way forward?should I build a replica phil read honda britain I know that's what is was because I've scratched the black paint off in areas and it's all red or return the bike to standard,cheers Bob
