Hi Todd, thanks for the e-mail. I think you could use a double stepped header. 2" x 2 1/8" x 2 1/4" with a 4" collector and I would keep the 2" very short, probably 6" to 8". I would need some dimentions for the pan and oil lines. That head is 1" wider than a 23 degree head and the ports are raised almost a 1/2" so you will probably have to relocate your steering column slightly. Other than that it should be no problem. Thanks again, Dan Lemons.
