It's usually good to keep the pushrods matched to the components at each end of 'em,mainly because they wear a pattern to each other,and swapping them around could cause accelerated wear while they develop a new pattern. I suspect in this case the only problem is likely to be that you'll have to adjust your valves a couple more times to compensate for the extra wear. I don't think I'd worry too much about it.
