I'm going to install an Offy dual port intake and a Weber 32/36 carb and after reading some of the treads I am confused at what all extra I might need. For anyone that has done this please advise me what extra parts I need to get verses those I might want to get, such as a fuel regulator or a PCV breather. I can't tell if these are needed or just something I might want to get. Also for those that did this install did you get the results you hoped for? I'm hoping for better gas milege and I little mor umph. Thanks
