Yep I had the same problem with the headers so I just opened up the holes a bit. This past Winter I built a new set of headers. The old headers were killing the engine's performance. The tubes were too small, so I built a set of 1 7/8" headers, had them coated, then wrapped. I have trick flow high port heads, trick flow also makes header flanges, so all you do start bending and welding tubes.Wow what a change, well worth the time. Had to increase the jet sizes and advanced the timing a bit. Picked up about 30+ HP. Plus now it has a much deeper rumble.
