I got in the habit of color coding things when I was racing. It sure makes it easier when you are working with someone. That is why my oil items are red. "Honey, get out and see if there is a leak around the red can on the bottom......" or "You put the oil in the red cap, not the black." I used new gaskets, and the Permatex #2 sealant. I like to use an O-ring at the base of the distributor, instead of the fragile cork circle. I also place O-rings under the valve cover holding hardware, and at the base of the breather cap.
