Lots of modifications. Plus the 250's aren't real easy to find. I would advise to do a P7P on the head, or go with a better head and have Tom do the porting, big bore kit, a nice cam and DIY exhaust header. You can, and might have to, go with a bigger carb with all those mods, but I would try the stocker first. The big drawback to the stock type pipes, is that they aren't port matched, and sometimes have rough bends. Find some mandrel bent pipe and weld up a nice transitioned head pipe and decent muffler, and you should be set.
