Engine cylinder head with valve cover off showing varnished cams…

Cylinder head with the valve cover removed, exposing a heavily varnished single overhead camshaft, rocker arms and valve springs coated in dark brown oil residue. The camshaft timing gear is visible at top with a hand resting on it, and the valve cover gasket rail shows baked-on sludge.
