Default HO or EFI?

Well i am about to purchase a 91 Stang 5.0 and its got a holley 4 barrel on it, should i keep the carb or go fuel injected? I know that HO motors have about 75+ more RWHP than a EFI. Whats better in the pair? Hit me back.

ho is the firing order. 351w firing order 13726548. fuel injection will give you a lil more hp but a lot better throttle response.
