Head casting number F5TE?

[Lab Rat]

OK- I'm in touch with a guy who says he has a set of heads from an '88 stang, but the casting numbers (he claims) are F5TE. Anyone even heard of this casting number in relation to a Ford head? I might be displaying my ignorance here, but I've heard E5AE, E7TE, F1ZE, F3ZE, F77E, etc, but never F5TE. Somebody educate me!

By the way ford makes casting numbers, that would make it an 95 truck head...
