Quote: I had the same issues with oil all over the place when removing the valve covers, a real pleasure when adjusting valves! Also, what a treat changing spark plugs. The easiest way I found was to plan on dropping the headers every time!
Or just whip-up a custom set of headers. Also, I ground a channel around the valvecover rail AND added a small drain port intersecting the botton of edge of the valvespring seat. The fitting can be seen in the pic just below the valvecover hold-down stud.
