Stopping the knock: Lower compression and ported heads...

Wish I could get my hands on this one. Something is being missed (data) or not relayed accurately. Everything sounds like it has been addressed but something clearly is out of whack. That big solid may not be nearly as big as you think. I bet the intake valve is closing too early for the combination. You could easily crutch this combo with an MSD 6al-2 and program the spark curve accordingly. Hint: It won't look anything like the ramps we are used to seeing. It even comes with a plug in for a MAP sensor so you can design a cruise ignition curve tailored to manifold vaccuum.

Now that it's apart--Tighten the quench.
Use a head gasket as close to bore size as possible
Make sure exhaust is not restrictive
Keep intake manifold and fuel lines cool
Get that **** on an engine dyno with someone who know Mopars!!!! J.Rob
