Ok, I've posted on here before about my coolant leak that I couldn't find and I didn't see coolant in my oil, but here are pics the valve covers and the rockers, etc. If I run my finger on the lifter valley, there is a lot of basically I guess it's sludge. It's very thick.

Am I screwed?? How can I clean this?? Does this mean damage to the engine? If so, what??
