No, no blackening.  But I figured if there was any, it would be smeared around during removal.  I also doubted htis could be an issue, and not fully convinced it is yet, but they ways things are pointing...man it is suspicious.   

Running points with an MSD 6A and a stock distributor.  I had a Pertronix, but it conked out on me. Again.   From other boards aorund, it seems like it is not uncommon for them to randomly go bad.  So I'm tired of replacing them and since I have an MSD now, all the points are doing is sending a signal to the MSD to do it thing.  So I've been running them with good results.  

Drove fantastic for a few days, and for a week it would fire up with outly 1-2 seconds of canking and no coaxing.  Sat 2 weeks, and then nothin'.  Not even an almost hit.  Even when jumpers are conected to a runing car.  Literally all I did during that 2 weeks was push it in and out of the garage 4 times to polish, wash, and wax.  When I pull plugs or ground the coil, it fires spark while cranking.  Cranking with the timing light attached shows timing is ~12 deg. I pulled a valve cover and checked the distributor is not 180 out and the valves are still moving, even though there was no way it could have had an opportunity to do otherwise.

Well, I've learned over the years that what often seems impossible ends up not being.  I have to admit that with the circumstances you presented, I'd pull those plugs and remove the anti-seize and try again.  It's still hard to believe that at the extraordinarily thin coating the compound would be reduced to, it would either electrically or thermally insulate the plug.  But hey...

As far as using anti-seize in the aluminum heads, is it really necessary anyway?  The only time I've heard of problems with plugs mating to al heads is after being left untouched for many miles, like 100K.  If the anti-seize is causing your starting/drivability problems, run them dry and just pull them every 10K or so.

If you have to have anti-seize stop by the electrical supply house and get a product called penetrox just use a dab on the threads don't paint e'm this stuff promtes conductivity its used mainly on conduit joints.

I've been using Antisieze on my daily drivers caliper bolts for a while now.  Makes the bolts come off a lot better for the next brake job.

Same here, but not quite for 30 years yet.  Have had zero problems.

What coil are you using?  I have a huge Mallory coil with MSD-6A Digital ignition and distributor.

And here is another thought...  Could it be the problem is the plug wires and when you remove them to change the plugs you move the wire connections so they work for a while?
  Just a thought... Sometimes the suspected problem is not caused by the suspect.
