Do you mean a ford racing head?
I am not exactly sure of the minor differences but I am 99% sure you dont want the SVT head. The head was set up with VCT on the intake port which you would then have to disable. the time and effort in that it would be better to get the stock head with a valve job, larger valves, new springs, and a slight decking.
