a hot rod guy (chopnchaneled from the HAMB) gave me this tip about the spark plug boots on the wires:
What causes that is when you pushed the boots on the plugs there was an air pocket formed in it and after a period of time pressure builds up and blows the wire off.
What we did to keep it from happening on the race engines was take a needle and syringe after pushing the boot on and slide the needle in the boot beside the plus and draw a little vacuum and it solved our problem.

Makes sense to me on the part about the wire popping off anyway.
Still not sure why the plug broke... I guess I'll keep an eye on it.
