Default Here's what MSD tech support said...

"What you're seeing is caused from ioized air inside the distributor cap as a direct result of the high powered CD ignition. The ioized air will attract moisture which over time can cause some corrosion like you're seeing. You can help this by venting the distributor cap. Drill a couple of 3/8" holes on the side of the cap between the towers at rotor height. Go ahead and clean off the 8 paddle reluctor wheel, but the pickup should be replaced. Over time, the rust can cause the pickup to become magnetized in a way that would adversely affect the performance. The part number for the pickup is 84661. "

Ordering a new pickup from JEGS - $17.99. Think I'll just get a new distributor cap and rotor while I'm at it.

Then:
- validate TDC
- Install new pickup and rotor
- Lash valves
- New air cleaner
- Set timing

Then, back to dyno to jet carb and test and adjust above. Interested to see what HP/Torque I can pick up on the cheap.
Thanks!
