Hi, for street use how much power would I gain by switching to the larger valves? The heads have had medium porting. Is it worth it for the street? If worth it what is a rough estimate of the cost?

If the valves are recessed, installing larger ones will automatically bring them back up nice and high.

If not, as far as performance is concerned, I don't think stock Ford heads can really take advantage of valves much larger than the 1.84"/1.56". You might gain a little, but will have to do a little valve unshrouding in the combustion chamber and open up the bowls a bit to take advantage of the larger valves.

Good Luck!
