This is why if the engine will not be started for a month or more you should put engine at TDC to unload valve springs.

I can understand that for number one... but what about cylinder 4 when 1 is at TDC?
lets say the Firing Order is 1-6-2-4-3-5 would it not stand to reason that the number 4 is at btdc and sucking in air with full lift? maybe I'm just reading too much into it.
