How to adjust the valve adjustment sequence of Aoling pickup 483Q diesel engine?

Hello, landlord! I am a professional truck mechanic. It depends on whether the air intake comes first or the exhaust comes first. First, turn the engine to the upper fulcrum of a cylinder. The four cylinders of your car have eight valves. If the air intake comes first, adjust 1, 2, 3, 6 ... If the air is exhausted first, adjust 1, 2, 4, 5, and then turn the engine to adjust the rest. The air intake gap is good. thank you
