351 windsor heads what years would work

Hi I got a 1996 f250 4x4 with the 351 windsor. And in to process of freshining up the motor I found that one of the heads acually rusted through on the cooling ports which has me worried as to how thin the rest of them are. Theres a good set on craigslist for 50 bucks but there from a 1993 f250 351 windsor. would they work and if so what other years would work. Thanks

Are they both fuel injected?
