Get a set of hedders. Heddman Elites are very nice. Scrap the chip idea, and get some high flow runners, and a lower intake and port the upper to match the runners. After that, get a cam, and gasket match your heads. The 113 heads on 88+ are a nice portable head. Get a true dual exhaust and you will be very surprised how much gaing you will get. Trust me I have done it all before.
