Where is number one cylinder on a V6 lexus es300?

Sorry to say my alldata doesnt list no1 cylinder ,but engine can be timed to any cylinder ,1 to 6 without any timing marks but you would need to have studied at college for 6 yrs like me to do this but trust me its not complicated ,bring up any cylinder to top then look at the cams ,if in doubt ask a local mechanic to have a look dont play as if its wrong you could bend the valves and in extreme circumstances knock a hole in a piston crown
