I've always liked the Tange Levin headsets and the CDS model is my go-to for short stack applications. My advice would be to avoid using a short-stack head set if you can avoid it. There are many more options for regular height H-sets so why restrict yourself. Proper sized crown races can be easily found or your fork can be machined to fit what you have. A fork race cutter can make it smaller and a knurling tool can make it bigger.
