The FA20E and FA20F engines have a cast aluminium alloy cylinder head with chaindriven double overhead camshafts per cylinder bank. The four valves per cylinder two intake and two exhaust were actuated by roller rocker arms which had builtin needle bearings that reduced the friction that occurred between the camshafts and the roller rocker arms.
