Valave cover gasket replacement

[Wilkechr]

Hey yall I'm about to replace the valve cover gaskets on my 2008 5.7 dodge ram. I was just wondering what should I look at while the covers are off I routinely change my own oil as I work at an auto center but I don't know much about what's under the valve cover. Is it safe to clean while under there? And what should I use? Any tips would be greatly appreciated

Before you remove valve covers blow off the entire area with compressed air so you dont get dirt inside engine ect not much to see however it will give you a good idea how clean your engine is if it has sludge or not.
