Yea, the grooves are normal.
The syncro to gear clearance looks pretty good from what I can see in the pics without being able to move it and feel it, and the teeth all look pretty good.
The crowns on the syncros look slightly rounded, but not bad.
I'd check the front and rear bearings, put it in and run it as see how it does, since they are so dog gone easy to R&R
