Print this out to a full page size, tape it to a cardboard box and push the bolts into it as you remove them. Greg suggested this and it works great. The Technical Corner has a nice write-up for that procedure (Thanks Greg!). Get some gray high-temp permatex/RTV sealant for reassembly.
Thanks Rob, and if I may add caution here....
Electrodude called this a "rocker cover". Wrong idea. Don't think of this as a cover on an old V-8. It is, in fact, an integral part of your overhead camshaft. It retains your camshaft and the rockers mounted in it. Therefore the operation of and forces of the rocker arms and valves are supported by this "head cover".
Therefore it is important to follow any steps that are needed when working with the camshaft and valves....such as setting the engine at Top Dead Center on the Compression stroke.
