If you get it dynoed, or one of the test people, with and without, I will 100% surely buy one, or send mine to you, however you do it. Im sure the Y pipe and throttle body flange and throttle body would definatley benefit from being ported like that. All that nice work they did on the head just to squeeze it through those 2 tiny holes!! But Good work. Has anyone ever tried getting rid of that flapper in the intake? It is supposed to make it more torquey in the lower end, But seems like it might be a restriction. And im not sure if it opens or closes at high end, Any input?
