Fairly new 350, less than 500 miles on it I suppose. I seem to have a small amount of oil on my spark plug threads. The heads are brand new sportman II's ported. The plugs themselves look great in color. And the car runs awesome. I was curious about the light oil on the threads. Could the rings not be sealed up yet? Also my timing bounces between 13 and 16 at idle with the distributor loose while I'm trying to set the timing. Then when I tighten the distributor it stays steady, is this normal. Thanks, Erik
