Yes all the modular heads(except off the V10,natch) will interchange. You should do a little research though as some production heads are better than others,depending on application.
all mod v8's fit. pi's are fair. 3v's better, 4v best. but finding an intake to work with hp is expensive. i passed up a 5.4 4v because it had a navigator intake.
all the V8 modular heads will work? what kind of project you thinking of? I don't know of any 2v intakes for the 5.4 but i have seen a few for 4V heads. One was for a carb setup. that would really simplify a 5.4 swap.
