I have a question about reversing the head on my march pump, now that they're bolted up, one has outlet pointing to floor and I need to change it . I assume you simply remove the screws, but I don't want to make and error and ruin it.

Just take the four screws out and rotate, retighten. The March is well built, you'll see it has brass inserts for the screws so it can be taken apart over and over without fatiguing plastic threads.
