Default Dirt under valvcovers (pics)

Just removede my valvecovers, and at the top of the heads I found this. It looks like old paint that is falling of in flakes. Is this normal?

Pretty normal on high comp. engines or engines that run hot or high mileage engines. It is a combination of varnish, carbon and oil byproducts that have cooked off.

An oil change NEVER hurts! But it won't keep the buildup from happening again.

Some claim the synthetics will not cook off like that... but in my experience with high temp. air cooled turbo-charged aircraft engines, you still get residue.
