Remember, unless its a new(er?) direct injected engine (or a diesel engine) the fuel gets mixed in with intake air before it actually goes through the intake valve..so it kinda makes sense that the flames would hang out near the intake valve (more fresh air/fuel mix in that location)
Illustrates how inefficient (or very efficient compared to 20 years ago) Internal combustion engines are.
