Ok, I did the spark test and it was a nice consistent spark at about 1/2 -3/4 of an inch away from the manifold as I eased back it would spart to look just like my timing light. It looks good to me but Im not sure how far it should jump. FYI make sure your pliers have real insilation. the first set had some kind of rubber but I guess wasn't good enough. Just enough zap for a good laugh though.
