Default Rocker bolts alignment - why not the same height?

Hello. I´m mounting my rocker arms and adjusting valves. Did all by the book. (Lars Grimsrud instructions). When finished I notice the rocker stud bolts are in different heights. Took a look at my original heads, and noticed the same difference there. Could anybody explain why? I thought the same ground circle, lifters and the pushrods would give the same height......

Are the rocker studs head mounting points the same?

Are the push rods the same length?

Are your 7 other in the picture rocker trunions mounted upside down?

do all your rocker nuts fit down in the rocker trunion machined area?

Does that shorter one allow the valve to fully close as adjusted?
