Help please, plug reading wizards!

Listening to all this internet overthinking guru crap is what got this problem started... Almost zero k.i.s.s..... this is supposed to be a grocery getter go to the dump get a load of wood simple truck and now we've went DEFCON 5.. rebuilt motor pocket ported heads custom cam four barrel intake headers fancy ignition this is nowhere in the k.i.s.s. range anymore...
Personally I'm more interested in the rod knock and waiting for that thread to start and see where that goes...
