Ford injectors? 90's model Grand Marquis

[xj_maniac_newb]

Have ran across 8 injectors from a 90's model grand marquis with the 5.0. What pound would these injectors be? I've did lots of research and have yet to find out anything about them.. They are gray, and seem to be the same style as the orange and blue injectors most usually get. Any idea if these will be an upgrade? I plan on cleaning them, so if they're even a small improvement i'll be happy with it

According to this they are 15lb injectors. By the way, that is the top result when you google "Ford 5.0 gray top injectors". Google is your friend.
