zzr1100 01 engine upgrade

Hi Everyone, very new to the KSRC and have already found some good ideas and info here. I have an 01 ZZR1100 which has done 96000Km's and i would like to give it a 'birthday' and get the engine freshend up, where would be a good place to start? I was thinking getting the heads cleaned up with new valve guides and the like, plus a rebore and wiseco bigbore kit. Does anyone know of a good shop i could take it too around the SE of Melbourne? Even if i need to take the engine out and take it too them. thanks
