The 3.0L valves will fit the 2.5L heads with out any problems. The overall length and the stem diameters are the same between the valves. I think all you need to do is bore out where the valve seats sit, and then open up the ports in the head to match. Everything else should be the same as a regular valve job. I bet you would use the same valve seats that the Taurus uses to. That would make the seats easy to find for the machine shop that is going to do the valve job. You basically need to have the ports opened up to do this. Why not go all out? Have the heads ported all the way. As soon as I get my hands on a good set of heads that is what I am going to do to. I have the bigger lower intake already. I'm just going to have the guy I use for port work open the intake and exhaust ports up to the edge of the gaskets. Then I'll have him port match everything else. I may even have him match the horrible stock exhaust manifolds to the heads if I don't have the money for headers in time. I think 250@ the wheels is possible with a 3.0L. It's my eventual goal. I would like to see it with stock cams. My car with a 3.0L, the big lower intake, an open intake and a SHO Shop Y-pipe made 215 @ the wheels through the STOCK exhaust!! I had a set of U/D pulleys to. There has to be 35hp in there.
