You don't flow heads at 2500 to 5500.
They are "flowed" on a "flow bench".
I am a "Head specialist".
I am not trying to "toot my own horn" but I am a little knowleable with cylinder heads.
Try www.e-squared-engineering.com
A 461 heads port volume is only 155cc give or take a couple cc's.
A common 882 open chamber head has a port volume of 151 cc.
I am not going to argue the point any more either.
If you don't believe me buy a chemist berret and cc away.
