I absolutely agree.

I pulled the cam last night, and the journals were a bit rounded (those 2), but not as bad as I expected. Although it is pretty hard to tell if the shape has changed.

If I were to pull the engine, I would have to disassemble completely to do a flush, right?

I would also have to send it to a shop (at least the best way would be to do that) to have it flushed and cleaned? (Hot tanked, etc).

Man it's a lot of work & expense but it's the only way to do it, dissassemble,hot tank, new rings and bearings. buy an engine cleaning brush kit and clean everything with hot soapy water, those brushes and air, when you reassemble use cam lube on the cam & lifters...
