Ok guys here goes hope this works. I use ngk plugs cause they work better for me then delco plugs. I have certain header tubes that will not clear delco plugs but clear the ngk plugs. Everyone has there picks but the delco 45ts and the ngk 6630 both gapped at .045 work the same for my engine with no difference in mileage or performance. Hope the picture works. I will have to hook up my timing light so see what the vacuum advance is doing at idle will get back tomorrow on that one.
