Yeah thats about what I did, so its cool! I used to changed the plugs on my topaz all the time to find the best ones, so I just got used to it. The only thing was when I first did them on the contour, I was not used to how hard it was to get at them on the Dura and how clean everything was. I ran around with a blown heard gasket for a week and didn't do any damage other then nearly gave my self an oil change, went down 3 qrts!
So everything was dirty as hell even after two people cleaned the bay out as good as they could....for free....
