Volvo Penta MD2020 - 3 cylinder valve adjustment

According to the manual, the valves must be adjusted every 400 hours. My engine has gone 800 hours and I don't think it ever has been done in it's lifetime.

Valve clearance in/out : 0.20 mm.

regarding the tension of the screws they must be good hand tight, according to the manual "DO NOT OVERTIGHTEN"
