I can not speak for the 1JZ-GTE VVT-i but the 2JZ-GTE VVT-i head is the exact same as 2JZ-GTE in terms of headflow. The gaskets are identical.
You must also know that headflow isn't the end-all, be-all point. The manner in which air mixes with gasoline is also of critical importance. I believe the proper term is atomize. Toyota designed the GE heads to atomize the air best under natural vacuum and the GTE under boost. Because of this fact the 2JZ-GTE is a worthwhile upgrade from the 2JZ-GE even though the headflow charts make them see almost identical.
