There does seem to be a bit of sludge along with the snot from the coolant leak. I'd just use some brake cleaner and clean what you can off of the rockers and valves covers. If you really wanted the valve cover clean you could take them to the car wash and blast them or a machine shop and have them tanked. After a few oil changes what you have in the engine will be gone for the most part. I wouldent worry too much about it.
