Just finished replacing my stock valve covers on my 88 L-98 for the second time in since 1988. I bought the paint to refinish the covers to make them "look" like stock. This paint will last up to 10 years. My covers have 4 bolts that are in the center of the cover. I managed to get the drivers side cover on without removing the wiper, only the electrical plug in the front. The problem is the fuel injector wires are thick and in order to get the cover on you have to pull the wires back as far as possible and mount the cover at the wiper side first and then it will fall into place. It takes some pactience believe me. Sorry I can't shot you a photo. The paint will make it look factory but not shiny.

Sometimes with taller valve covers the wiper motor interferes. You have to notch the corner of the cover and have it welded back together. Sometimes the alternator also has interference, but that might be limited to LT motors.

I would think the issue with tall covers would be the EGR pipe that crosses the passenger side cover, and the A/C compressor as well. On my 91 those two places arecertainly an issue. I've decided to just have a set of stock covers ceramic coated silver instead. Cheaper and no fitment issues.
