In my younger days, I rebuilt a few gasoline GM engines, and was used to this procedure. I was surprised when I rebuilt my first 6.2L! And then I grew to appreciate the "install it and forget" nature of the fixed-type hydraulic valve-train.
Much better than the Cummins, Toyota 22RE gasser, and other similar setups that require periodic valve train adjustments, in my opinion.
