Just as any 4 cylinder. I cant remember so i allways do it per valve, turn a bit further than when it closes, adjust and turn on till the 2nd valve closes. This way i do them all from back to front.
You could do all while the engine is in two positions, but i cant remember, i adjust valves every 5 years or so, so its easier to do it my way, than trying to remember how the "fast way" works before you can do any actual work
