Again you brought his car into this discussion not me.

Again, there is more to a race car than the heads. A bad converter alone could do what you describe. Why do you assume it was the heads? If the engine MADE 150 hp more, it sure sounds like it was something else. This is amazing to me. Is there a 101 class for racing here? Sure seems like some folks need to start back at the beginning.
