I use that exact gas block on several builds because I don't like set screw blocks anymore. I actually noticed an accuracy difference when I took a set screw block off and put the yhm on. But, I modify that block with a set screw to make it adjustable. If you're handy with stuff like that, drill and tap for a #8 set screw through the side and right through the gas port hole. I install the gas tube first as you will go through the very bottom edge of it also.
The tricky part is getting the hole threaded deep enough. A blind hole tap to finish it would be great but haven't found one yet. And go slow and don't break the tap, I did that once and it's impossible to remove it.
