Build concrete filled masonry block arches without a template

Cut all the blocks before construction. The cuts (all halfs) that form the arch and their off-cuts are numbered identically. Take the opening to spring height, then using a standard head support, go across the head, laying each cut in its place, its off-cut on top, and a membrane (aluminum flashing is ideal) between the two. When the wall is core filled, the flashing around the arch line stops the concrete. Remove off-cuts and extra few blocks To reveal arch.
