Interesting problem with your distributor. I haven't had to rework a reluctor for a long time!
What does the port match look like on your intake manifolds? On my 470 none of the intakes I had on hand were close in terms of port matching. Engine still made 685 hp with mis-matched ports but I'm looking for more once I get the intake cleaned up. Here is what my Mopar intake looked like. The Victor intake was even worse.
