Default Head info needed,2.5 2003-2004 JDM DOHC w/AVCS

Hello all as you can see I’m a noob with a question.

I’m wondering if anyone happens to have a flow chart or knows the CFM of theses heads.
I have very little info on the head other than they are from 2001–2004 JDM Legacy RS25 with 2.5L NA and AVCS. The ports look huge compared to my 06 FXT head.

It's hard to find flow information for heads common here in the US, let alone ones that aren't available here.

Some of the guys in the Built Motors Discussion forum might be able to give you some ideas.
