the ports are slightly different and one of the water jackets need work. When I bought my intake from Joe Charles @ Parkway, he suggested Charles Rogers(?) @ Heads Up. The water jacket required some welding and then reshaping, and then the ports are just gasket matched, sorta. Total it cost me. 265.00 However, After seeing what all was needed, I would think almost any good machinst/headporter whatever, could do the work for ya!
