The theory on exhaust is less back pressure is more HP up high, less torque down low...Something you might try is shaving the head to increase compression. Now, my experience is limited to driving the vehicle with the increased compression. I have not driven one that is stock, so I can't say for sure how much of an improvement you would receive. But I can tell you that shaving .030" off the head is doable, and it lasts with the timing set properly. The previous owner of my 'Kick had overhauled the motor and had the head shaved. He has done this on 2 'Kicks, and had no longevity issues. He said the performance increase was significant. Is yours a 16 valve, or 8 valve?
