Pretty awesome - I think.

Looked like a lot of pitting on the underside in and near the combustion chamber. Was that a really rough surface? I'd be a little concerned this could be a place where carbon deposits might be allowed to form - ultimately causing predetonation. Anybody else have any thought about this possibility? I'm sure if it was still Rob who works there, he'd have said something if it were a problem. I'm a bit picky too. Shave too much off and you'd have problems too.
