318 MAX fuel economy builds?

I don’t see ported J heads or any ported head needed for this mileage build.

What I do see as far as cylinder heads go is a stock head given a awesome valve job and that’s it.

Induction wise above the head is any mild dual plane intake.
Carb, small primary unit. The small AVS II 650 is fine. I’m with Bewy on a small primary TQ.

I checked out those cams. They are pretty close to what I'm looking at after the Rhoads lifters reduce my duration 15 deg at .050. Kinda tells me I'm on the right path. I'm not porting J heads. The entire thread is about super high mileage. I'm hoping the increase velocity atomizes my fuel better than with the J heads and with superior quench maximizes the engines efficiency ay low rpm. I'm trying to get max mileage and still have a lil power from 3000 to 5000. If I don't get 325 hp that's fine. kinda. lol
