I've wondered what goes on inside the plenum, is post #52 stock inside?

I would think there could be some merit in taking an approach found on SHOs and late four-valve 4.6s: differing runner lengths for the 2 valves.

Adding something like a french cut exhaust tip on 1st, 4th, 5th and 8th runner one side, maybe 3-4", with the opposing one offset to the other valve. Hope I'm describing this reasonably.

Just a thought,
- Jeff
