help with exhaust problem 99 ranger 2.5l

[ranger heat]

I rebuilt a 99 ranger 2.5l, head was cracked so ordered new casting from calif company, install everything and last to bolt on was exhaust manifold, manifold was leaking so pulled off to check gasket and realized that the ports on head did not match up with ports on mainfold so I am now looking for new mainfold that will line up with new head casting ( casting number is F 57 E ) where do i go ?
