I am curious how much is can be punched out. Probably stroking it isn't a good idea, it would add torque but sacrifice high end hp. A basic recipe is to punch it out to the biggest after market pistons available for the motor. Have the crank balanced for a smoother idle and quicker revving plus a little more power. Make sure to use higher compression pistons, but not too high unless you want to run nothing but race gas. Keep in mind you can't adjust the ignition timing without a stand alone EMS, or msd6 modules plus two tach adapters, or a custom tuned chip, so don't get to wild with the compression ratio. Use total seal rings, they work great. As for the head an extensive port and polish plus bowl work, street cams, plus gears. Also you might need valve springs depending on the cams, don't get the springs unless the cams require them because you will loose power. Get titanium retainers and valves if within budget. Definately a header is in order. I would wait on the intake until more people have tried it unless you don't mind experimenting. Anyway that should net you some gains.
