Summit brand 1.6 roller rockers installedMy 1992 had the factory magnesium valve covers, which have to be modified slightly for the roller rockers. I did not take pictures of the valve cover modification (brain fart), but it is easy... just use a Dremel tool, with a cutting wheel, to remove the oil "drip tabs". If you search the Internet you can find pix of people who have done this. Cut the drip tabs flush with the inside of the valve cover. Also, the valve covers were showing their age, so I cleaned them up and repainted them with "wrinkle" paint to hide some of the pitting and general crummy finish they had.
