Im pretty sure all the late model lsx heads are going to be aluminum, but no you shouldnt have any problems. You'll still want heads that will flow well and your partially right in that its not nearly as big of a deal with FI. Tim could explain the velocity vs. cfm thing alot better then I could im sure...but i know in NA applications you want the smallest port with highest cfm...having a large port and high cfm usually gives you far less performance in an NA application though.
