Cool question, I'd like to know. ALSO, are there any benefits to doing that head swap? Do they breath better? Bigger valves? anything?

Not a 100% sure, but from what I have seen and know, I would have to say no. Sure it will bolt uo to the block, but I think that is it. Now lets say you mod the GE manifolds to make them bolt on the GTE head. But, one more issue. The valve system is way different from the GE head, so you would probably have to run a stand alone because the GE ecu will not work with GTE head.

No, they are different. Either head is interchangeable on the 2JZ block. However the GE and GTE heads have different intake and exhaust port shapes. The turbo head has narrower ports for higher velocity to spool the turbo. the NA head has smoother larger ports for better flow. They also have different bolt patterns and port spacings.
