No, they are not equal. an equal displacement V6 has less unshrouded valve area, and total valve area. if the V8 is restricted it will make the same power, ie small throttle body designed for the v6.
8 ports that flow 300cfm vs. 6 ports that flow exactly the same is the difference.
i will guarantee you that a Turbocharged supra inline 6 will not make more power per pound of boost than my ported head turbocharged 4.6 dohc 4v or your LS3.
fully ported 2JZ heads only flow 289in /180ex @ 28". as big of a legend as they are, they are not anything "special". stock 2JZ ports only flow 233in / 159 exhaust. they dont make more power per pound of boost than anything else out there. airflow is airflow. pounds per minute and BSFC decides everything.
