I glossed completely over the header issue of the 400 swap, glad you brought it up. Something else for Gary to think about. You're sharp, and very gracious about sharing your knoweledge.
I haven't flowed the AFD heads. I have read good feedback on the Cleveland engine forum re the AFD heads. I perceive them as an improved aussie 2V head, without the intake port limitations, cast in aluminum, and without the aparent intake/exhaust manifolding hassles of the CHI heads.
I admit it is a personal taste issue, but I wouldn't want an induction system poking through, or a hump in my engine screen. An AFD 2V head & Weiand 2V Xcelerator are a low profile combination that are ideal for the rpm range of the "street" motor I would build for myself or recommend for someone else. They replace the A3 heads & A331 manifold (Edelbrock version) I recommended in the past. Admittedly the Ford Motorsports high port heads have greater flow potential. But the Cleveland engine scene has reached a point where folks are building 500 bhp at 6000 rpm with Aussie heads on 377 cu.in. strokers. Thats about 80 bhp per liter. That should keep the Pantera competitive on the street.
at my age, do I need that much car? .............no.........yes.....no........yes
Would I build another motor with A3 heads & an A331 manifold, if I had them? ..........Yes
