Here’s a quick look at the process. If the curves are mild, then use a mallet and chisel. If the radius of the curve becomes so tight that the angled edges of the blocks touch, you would have to cut the edges to a sharper angle to prevent gaps in the joints from showing. Your other option would be to start with a larger radius curve on the bottom course, so the edges of the blocks will still meet at the top without cutting. Cutting a block in half or using the half width blocks, will assist in creating a proper offset. maybe even put a tick mark that crosses both the cap and wall so you know where the piece has to go once you mortar it.
