(trying to figure how only one valve gets hit)

The decomp only cracks open that one valve under normal conditions and at low rpm starting speed it doesn't hit the piston...crack that valve open at idle or higher and it will tap the piston. It only took a few seconds to carve out the gouges we can see and that's when the valve met piston.
