This is strange. My engine has been sitting for about three months. I pulled tha backplate to check the bearings for rust and they were perfect. On the crankshaft there were three very small touches of rust but other than that the engine was in great shape. Then I pulled the cyl head and this is what I saw.

Should I worry about it or just keep flying????

Just run the engine. The pitting might be corrosion. This isn't something we normally see. We usually see pitting that's resulted from foreign material or from severe detonation. Also, we always heavily-lube all engines after running them.
