Of course, those simply starting the car up are free to do what they wish, and for most, there won't be any negative repercussions.
But, I still recommend (and I do) making sure the drivetrain isn't siezed because it's not a difficult procedure and good insurance. Think about it, most headgasket failures are progressive, with many allowing coolant into a cylinder producing white smoke/steam. If you have such a small leak, over the months-long storage, the coolant seeps into a cylinder causing the rings to bind to the cylinder wall. A high-torque startup on the starter motor can tear the rings turning a headgasket replacement into a rebuild. Imho, turning the engine as I describe is a good way to avoid this because you never really know if any siezure has taken place until it's too late to do anything about it.
But, I relayed this specifically in response to the author's queery: " Are there any special procedures to do before start-up? "
Cheers!
