I am just getting into edge gluing to make wide boards, say around 18
inches. Each time that I try the finished board seems to warp across the
board. I am positive that the board was flat in the clamp and stayed
there
for a few days.

Should I use several narrow boards or a couple of wider boards? Is the end
grain at the end of the boards important?

What is important is the proper selection of your material, all the way from
the type, to how it was originally cut from the log, to the moisture content
when you use it.

And there is probably no better way to get a handle on that than:

You will do no better in your search for understanding the reasons for your
problem(s) with wood, guaranteed.
