EngineQuest LA pattern Magnum Heads (Australian)

Hey everyone, I'm still on the search for a pair of LA intake pattern Australian EngineQuest Magnum heads preferrably unported but hey beggars cant be choosers. The heads will have been cast and sold anywhere from 2009-2014 or so--the foundry shutdown in 2015. Surely there must be someone who pulled a set of these off in favor of the new Trickflows or something to that affect. Thanks in advance, J.Rob
