Whaddya think about these plugs?
That dual-plane + dual-carb intake is a South African item. So are these ones—the compound-plenum 4bbl was (??used, tested??) on some Valiants hot-rodded for police service there, and the long dual-2bbl setup was part of a performance pak I don't recall the name of. A Valiant freak down there, went by 68Barracuda online, was going to repro them, but then he seemed to fall off the planet; I haven't heard from him since 2014, so odds are against. :-(
