The EJ251 and EJ252 engines had an aluminium alloy cylinder head with cross-flow cooling. The intake ports for the EJ251 and EJ252 engines created a ‘tumble swirl’ motion for air as it entered the cylinder for better air/fuel mixing, more uniform flame travel and faster combustion.
The FA20E and FA20F engines have a cast aluminium alloy cylinder head with chain-driven double overhead camshafts per cylinder bank. The four valves per cylinder – two intake and two exhaust – were actuated by roller rocker arms which had built-in needle bearings that reduced the friction that occurred between the camshafts and the roller rocker arms.
