There is a gasket set from Felpro that has everything you need including the valve-cover gaskets. The most important thing is to get the gasket with the metal carrier. I also got new bolts for the LIM from Felpro. They were not that expensive.

For me, the most annoying part was having trouble finding a bolt for the lower end of the power steering pump bracket. If I had looked more closely at the directions, I would have saved myself a lot of time.

As soon as I learned that these LIM gaskets can fail catastrophically and ruin the engine, I replaced them.
