I should add that the only thing I reused on this new engine is the spark plug wires, they are around a year and a half old and since they've been running behind headers for that long it's possible that I've cooked one or two of them by now enough to cause issues during cold start and high humidity situations. So I just went and ordered me a new set of 8MM wires from Select, hopefully that'll take care of the intermittent miss on cold starts.

That said, I'm still wondering if I can or should run a hotter spark plug for the street, especially when colder weather returns?
