yes!
bigger carbs, and better pipes. fmfs aren't high end pipes, and adding the timing plate and keeping those pipes would be a waste. A timing plate will get you higher rpms. Port it, carbs, pipes, timing plate, and then it will run. and on the jetting,,,, you will defenately need different jets or you will be way way too lean I think. also while you have it apart measure stuff up and make sure it is a 4 mil crank! good luck!
